Fix its header comment, which described the old behavior of the <N>
phrase distance operator; we missed updating that in commit 028350f61.
Also, reset errno before strtol() call, to defend against the possibility
that it was already ERANGE at entry. (The lack of complaints says that
it generally isn't, but this is at least a latent bug.) Very minor
stylistic improvements as well.
Victor Drobny noted the obsolete comment, I noted the errno issue.
Back-patch to 9.6 where this code was added, just in case the errno
issue is a live bug in some cases.

Commit c2b1e01a made script name prefixes unique by removing the regular
scripts and only keeping the XL-specific ones (with additional conditions
on bid). That turned out to be an incorrect approach - I misunderstood
the XL code and believed XL only executes the modified scripts. But those
scripts are executed only when "-k" option is specified, and the regular
ones should be used by default.
This commit fixes this by reintroducing the regular pgbench scripts, and
addresses the duplicate names by making the script names unique only when
combined with the '-k' option value.
It also adds an XL version of the 'simple-update' script with the extra
bid condition, which was missing in XL 9.5 for some reason.

pg_import_system_collations() refused to create any ICU collations if
the current database's encoding didn't support ICU. This is wrongheaded:
initdb must initialize pg_collation in an encoding-independent way
since it might be used in other databases with different encodings.
The reason for the restriction seems to be that get_icu_locale_comment()
used icu_from_uchar() to convert the UChar-format display name, and that
unsurprisingly doesn't know what to do in unsupported encodings.
But by the same token that the initial catalog contents must be
encoding-independent, we can't allow non-ASCII characters in the comment
strings. So we don't really need icu_from_uchar() here: just check for
Unicode codes outside the ASCII range, and if there are none, the format
conversion is trivial. If there are some, we can simply not install the
comment. (In my testing, this affects only Norwegian Bokmål, which has
given us trouble before.)
For paranoia's sake, also check for non-ASCII characters in ICU locale
names, and skip such locales, as we do for libc locales. I don't
currently have a reason to believe that this will ever reject anything,
but then again the libc maintainers should have known better too.
With just the import changes, ICU collations can be found in pg_collation
in databases with unsupported encodings. This resulted in more or less
clean failures at runtime, but that's not how things act for unsupported
encodings with libc collations. Make it work the same as our traditional
behavior for libc collations by having collation lookup take into account
whether is_encoding_supported_by_icu().
Adjust documentation to match. Also, expand Table 23.1 to show which
encodings are supported by ICU.
catversion bump because of likely change in pg_collation/pg_description
initial contents in ICU-enabled builds.

The maxResultSize argument of uloc_getDisplayName is the number of
UChars in the output buffer, not the number of bytes. In principle
this could result in a stack smash, although at least in my Fedora 25
install there are no ICU locales with display names long enough to
overrun the buffer. But it's easily proven to be wrong by reducing
the length of displayname to around 20, whereupon a stack smash
does happen.
(This is a rather scary bug, because the same mistake could easily
have been made in other places; but in a quick code search looking
at uses of UChar I could not find any other instances.)

Marco Atzeri reported that initdb would fail if "locale -a" reported
the same locale name more than once. All previous versions of Postgres
implicitly de-duplicated the results of "locale -a", but the rewrite
to move the collation import logic into C had lost that property.
It had also lost the property that locale names matching built-in
collation names were silently ignored.
The simplest way to fix this is to make initdb run the function in
if-not-exists mode, which means that there's no real use-case for
non if-not-exists mode; we might as well just drop the boolean argument
and simplify the function's definition to be "add any collations not
already known". This change also gets rid of some odd corner cases
caused by the fact that aliases were added in if-not-exists mode even
if the function argument said otherwise.
While at it, adjust the behavior so that pg_import_system_collations()
doesn't spew "collation foo already exists, skipping" messages during a
re-run; that's completely unhelpful, especially since there are often
hundreds of them. And make it return a count of the number of collations
it did add, which seems like it might be helpful.
Also, re-integrate the previous coding's property that it would make a
deterministic selection of which alias to use if there were conflicting
possibilities. This would only come into play if "locale -a" reports
multiple equivalent locale names, say "de_DE.utf8" and "de_DE.UTF-8",
but that hardly seems out of the question.
In passing, fix incorrect behavior in pg_import_system_collations()'s
ICU code path: it neglected CommandCounterIncrement, which would result
in failures if ICU returns duplicate names, and it would try to create
comments even if a new collation hadn't been created.
Also, reorder operations in initdb so that the 'ucs_basic' collation
is created before calling pg_import_system_collations() not after.
This prevents a failure if "locale -a" were to report a locale named
that. There's no reason to think that that ever happens in the wild,
but the old coding would have survived it, so let's be equally robust.

After sitting idle and fully replayed for a while and then encountering
a new burst of WAL activity, we interpolate between an ancient sample and the
not-yet-reached one for the new traffic. That produced a corner case report
of lag after receiving first new reply from standby, which might sometimes
be a large spike.
Correct this by resetting last_read time and handle that new case.

Callers of icu_to_uchar() neglected to pfree the result string when done
with it. This results in catastrophic memory leaks in varstr_cmp(),
because of our prevailing assumption that btree comparison functions don't
leak memory. For safety, make all the call sites clean up leaks, though
I suspect that we could get away without it in formatting.c. I audited
callers of icu_from_uchar() as well, but found no places that seemed to
have a comparable issue.
Add function API specifications for icu_to_uchar() and icu_from_uchar();
the lack of any thought-through specification is perhaps not unrelated
to the existence of this bug in the first place. Fix icu_to_uchar()
to guarantee a nul-terminated result; although no existing caller appears
to care, the fact that it would have been nul-terminated except in
extreme corner cases seems ideally designed to bite someone on the rear
someday. Fix ucnv_fromUChars() destCapacity argument --- in the worst
case, that could perhaps have led to a non-nul-terminated result, too.
Fix icu_from_uchar() to have a more reasonable definition of the function
result --- no callers are actually paying attention, so this isn't a live
bug, but it's certainly sloppily designed. Const-ify icu_from_uchar()'s
input string for consistency.
That is not the end of what needs to be done to these functions, but
it's as much as I have the patience for right now.

It's essential that initdb.c's setup_depend() scan each system catalog
that could contain objects that need to have "p" (pin) entries in pg_depend
or pg_shdepend. Forgetting to add that, either when a catalog is first
invented or when it first acquires DATA() entries, is an obvious bug
hazard. We can detect such omissions at reasonable cost by probing every
OID-containing system catalog to see whether the lowest-numbered OID in it
is pinned. If so, the catalog must have been properly accounted for in
setup_depend(). If the lowest OID is above FirstNormalObjectId then the
catalog must have been empty at the end of initdb, so it doesn't matter.
There are a small number of catalogs whose first entry is made later in
initdb than setup_depend(), resulting in nonempty expected output of the
test, but these can be manually inspected to see that they are OK. Any
future mistake of this ilk will manifest as a new entry in the test's
output.
Since pg_conversion is already in the test's output, add it to the set of
catalogs scanned by setup_depend(). That has no effect today (hence, no
catversion bump here) but it will protect us if we ever do add pin-worthy
conversions.
This test is very much like the catalog sanity checks embodied in
opr_sanity.sql and type_sanity.sql, but testing pg_depend doesn't seem to
fit naturally into either of those scripts' charters. Hence, invent a new
test script misc_sanity.sql, which can be a home for this as well as tests
on any other catalogs we might want in future.

The autovacuum launcher doesn't actually do anything with its DSA other
than creating it and attaching to it, but it's been observed that after
longjmp'ing to the standard error handling block (for example after
getting SIGINT) the autovacuum enters an infinite loop reporting that it
cannot attach to its DSA anymore (which is correct, because it's already
attached to it.) Fix by only attempting to attach if not already
attached.

When promoting a standby just after a XLOG_SWITCH record was replayed,
and next segment(s) are already are locally available (via walsender,
restore_command + trigger/recovery target), that segment could
accidentally be recycled onto the past of the new timeline. Later
checkpointer would create a .ready file for it, assuming there was an
error during creation, and it would get archived. That causes trouble
if another standby is later brought up from a basebackup from before
the timeline creation, because it would try to read the
segment, because XLogFileReadAnyTLI just tries all possible timelines,
which doesn't have valid contents. Thus replay would fail.
The problem, if already occurred, can be fixed by removing the segment
and/or having restore_command filter it out.
The reason for the creation of such "phantom" segments was, that after
an XLOG_SWITCH record the EndOfLog variable points to the beginning of
the next segment, and RemoveXlogFile() used XLByteToPrevSeg().
Normally RemoveXlogFile() doing so is harmless, because the last
segment will still exist preventing InstallXLogFileSegment() from
causing harm, but just after promotion there's no previous segment on
the new timeline.
Fix that by using XLByteToSeg() instead of XLByteToPrevSeg().

Don't move parenthesized lines to the left, even if that means they
flow past the right margin.
By default, BSD indent lines up statement continuation lines that are
within parentheses so that they start just to the right of the preceding
left parenthesis. However, traditionally, if that resulted in the
continuation line extending to the right of the desired right margin,
then indent would push it left just far enough to not overrun the margin,
if it could do so without making the continuation line start to the left of
the current statement indent. That makes for a weird mix of indentations
unless one has been completely rigid about never violating the 80-column
limit.
This behavior has been pretty universally panned by Postgres developers.
Hence, disable it with indent's new -lpl switch, so that parenthesized
lines are always lined up with the preceding left paren.
This patch is much less interesting than the first round of indent
changes, but also bulkier, so I thought it best to separate the effects.

Change pg_bsd_indent to follow upstream rules for placement of comments
to the right of code, and remove pgindent hack that caused comments
following #endif to not obey the general rule.
Commit e3860ffa4dd0dad0dd9eea4be9cc1412373a8c89 wasn't actually using
the published version of pg_bsd_indent, but a hacked-up version that
tried to minimize the amount of movement of comments to the right of
code. The situation of interest is where such a comment has to be
moved to the right of its default placement at column 33 because there's
code there. BSD indent has always moved right in units of tab stops
in such cases --- but in the previous incarnation, indent was working
in 8-space tab stops, while now it knows we use 4-space tabs. So the
net result is that in about half the cases, such comments are placed
one tab stop left of before. This is better all around: it leaves
more room on the line for comment text, and it means that in such
cases the comment uniformly starts at the next 4-space tab stop after
the code, rather than sometimes one and sometimes two tabs after.
Also, ensure that comments following #endif are indented the same
as comments following other preprocessor commands such as #else.
That inconsistency turns out to have been self-inflicted damage
from a poorly-thought-through post-indent "fixup" in pgindent.
This patch is much less interesting than the first round of indent
changes, but also bulkier, so I thought it best to separate the effects.

The new indent version includes numerous fixes thanks to Piotr Stefaniak.
The main changes visible in this commit are:
* Nicer formatting of function-pointer declarations.
* No longer unexpectedly removes spaces in expressions using casts,
sizeof, or offsetof.
* No longer wants to add a space in "struct structname *varname", as
well as some similar cases for const- or volatile-qualified pointers.
* Declarations using PG_USED_FOR_ASSERTS_ONLY are formatted more nicely.
* Fixes bug where comments following declarations were sometimes placed
with no space separating them from the code.
* Fixes some odd decisions for comments following case labels.
* Fixes some cases where comments following code were indented to less
than the expected column 33.
On the less good side, it now tends to put more whitespace around typedef
names that are not listed in typedefs.list. This might encourage us to
put more effort into typedef name collection; it's not really a bug in
indent itself.
There are more changes coming after this round, having to do with comment
indentation and alignment of lines appearing within parentheses. I wanted
to limit the size of the diffs to something that could be reviewed without
one's eyes completely glazing over, so it seemed better to split up the
changes as much as practical.

Currently, there are no built-in functions that are SECURITY DEFINER.
But we just found an instance where one was mistakenly marked that way,
so it seems prudent to add a test about it. If we ever grow some
functions that are intentionally SECURITY DEFINER, we can alter the
expected output of this test, or adjust the query to filter out functions
for which it's okay.

Commit 1d14325822 randomized the initial node selection with ROUNDROBIN
distribution, but that unexpectedly broke multiple regression tests by
changing the order of returned rows (or making it unstable).
In all the tests the table ends up distributed by ROUNDROBIN implicitly
as the particular data type (e.g. "line" or "jsonb") does not support
HASH distribution.
The test data are typically inserted row-by-row, so before 1d14325822
all the rows ended up of the first datanode, which made the query order
deterministic. But since 1d14325822 the rows are distributed randomly.
Wherever possible, the order is made deterministic by adding ORDER BY
to the queries, as usual. When not possible, because the data type
does not support ordering (e.g. "line" again) the table is explicitly
defined as replication.

load_libraries(), which processes the various xxx_preload_libraries GUCs,
was parsing them using SplitIdentifierString() which isn't really
appropriate for values that could be path names: it downcases unquoted
text, and it doesn't allow embedded whitespace unless quoted.
Use SplitDirectoriesString() instead. That also allows us to simplify
load_libraries() a bit, since canonicalize_path() is now done for it.
While this definitely seems like a bug fix, it has the potential to
break configuration settings that accidentally worked before because
of the downcasing behavior. Also, there's an easy workaround for the
bug, namely to double-quote troublesome text. Hence, no back-patch.

Viewing a table with \d in psql also shows the publications at table is
in. If a publication is concurrently dropped, this shows an error,
because the view pg_publication_tables internally uses
pg_get_publication_tables(), which uses a catalog snapshot. This can be
particularly annoying if a for-all-tables publication is concurrently
dropped.
To avoid that, write the query in psql differently. Expose the function
pg_relation_is_publishable() to SQL and write the query using that.
That still has a risk of being affected by concurrent catalog changes,
but in this case it would be a table drop that causes problems, and then
the psql \d command wouldn't be interesting anymore anyway.

David Rowley found that the "use the smallest per-column selectivity"
heuristic applied in some cases by get_foreign_key_join_selectivity()
was badly off if the FK columns are independent, producing estimates
much worse than we got before that code was added in 9.6.
One case where that heuristic was used was for LEFT and FULL outer joins
with the referenced rel on the outside of the join. But we should not
really need to special-case those here. eqjoinsel() never has had such a
special case; the correction is applied by calc_joinrel_size_estimate()
instead. Let's just estimate such cases like inner joins and rely on that
later adjustment. (I think there was something of a thinko here, in that
the comments seem to be thinking about the selectivity as defined for
semi/anti joins; but that shouldn't apply to left/full joins.) Add a
regression test exercising such a case to show that this is sane in
at least some cases.
The other case where we used that heuristic was for SEMI/ANTI outer joins,
either if the referenced rel was on the outside, or if it was on the inside
but was part of a join within the RHS. In either case, the FK doesn't give
us a lot of traction towards estimating the selectivity. To ensure that
we don't have regressions from what happened before 9.6, let's punt by
ignoring the FK in such cases and applying the traditional selectivity
calculation. (We might be able to improve on that later, but for now
I just want to be sure it's not worse than 9.5.)
Report and patch by David Rowley, simplified a bit by me. Back-patch
to 9.6 where this code was added.

conversion being done on the compressed stream. Switch stdout to binary
mode for this case, at the same place where we do it for non-text output
formats.
Report and patch by Kuntal Ghosh, tested by Ashutosh Sharma and Neha
Sharma. Back-patch to all supported branches.
