In commit 8bf6ec3ba, I mistakenly supposed that MergeAttributes'
loop over saved_schema was reprocessing column definitions that
had already been checked earlier: there is a variant syntax for
creating a child partition in which that's not true. So we need
to duplicate the full check appearing further up.
(Actually, I believe that the "if (restdef->identity)" part is
not reachable, because we reject identity on partitions earlier.
But it seems wise to keep the check, in case that's ever relaxed,
and to keep this code in sync with the other instance.)
Per report from Alexander Lakhin.

d9d7fe68d3 made use of an existing wait event when sending data from the
apply worker, but we should have invented a new wait event since this is a
new place to wait.
This patch corrects the mistake by using a new wait event
"LogicalApplySendData".

force_parallel_mode is meant to be used to allow us to exercise the
parallel query infrastructure to ensure that it's working as we expect.
It seems some users think this GUC is for forcing the query planner into
picking a parallel plan regardless of the costs. A quick look at the
documentation would have made them realize that they were wrong, but the
GUC is likely too conveniently named which, evidently, seems to often
result in users expecting that it forces the planner into usefully
parallelizing queries.
Here we rename the GUC to something which casual users are less likely to
mistakenly think is what they need to make their query run more quickly.
For now, the old name can still be used. We'll revisit if the old name
mapping can be removed once the buildfarm configs are all updated.

OpenSSL 1.1.1 and newer versions have added support for RSA-PSS
certificates, which requires the use of a specific routine in OpenSSL to
determine which hash function to use when compiling it when using
channel binding in SCRAM-SHA-256. X509_get_signature_nid(), that is the
original routine the channel binding code has relied on, is not able to
determine which hash algorithm to use for such certificates. However,
X509_get_signature_info(), new to OpenSSL 1.1.1, is able to do it. This
commit switches the channel binding logic to rely on
X509_get_signature_info() over X509_get_signature_nid(), which would be
the choice when building with 1.1.1 or newer.
The error could have been triggered on the client or the server, hence
libpq and the backend need to have their related code paths patched.
Note that attempting to load an RSA-PSS certificate with OpenSSL 1.1.0
or older leads to a failure due to an unsupported algorithm.
The discovery of relying on X509_get_signature_info() comes from Jacob,
the tests have been written by Heikki (with few tweaks from me), while I
have bundled the whole together while adding the bits needed for MSVC
and meson.
This issue exists since channel binding exists, so backpatch all the way
down. Some tests are added in 15~, triggered if compiling with OpenSSL
1.1.1 or newer, where the certificate and key files can easily be
generated for RSA-PSS.

Previously make_etags always ran make_ctags -e when make_etags was
executed. However, because non-Exuberant ctags on Mac does not
support -e option (and also on other platforms including old Linux),
ctags failed. To avoid the failure change make_ctags so that if
non-Exuberant ctags is used and ctags -e option is requested, run
etags command instead. If etags command does not exist, make_ctags
will fail.
Also refactor make_ctags and tweak make_etags to emit proper usage

In commit b78f6264e I opined that it was "too risky" to delete a
relation's RelOptInfo from the planner's data structures when we have
realized that we don't need to join to it; so instead we just marked
it as a dead relation. In hindsight that judgment seems flawed: any
subsequent access to such a dead relation is arguably a bug in
itself, so leaving the RelOptInfo present just helps to mask bugs.
Let's delete it instead, allowing removal of the whole notion of a
"dead relation". So far as the regression tests can find, this
requires no other code changes, except for one Assert in equivclass.c
that was very dubiously not complaining about access to a dead rel.

Late in the development of commit 2489d76c4, I (tgl) incorrectly
concluded that the new function have_unsafe_outer_join_ref couldn't
ever reach its inner loop. That should be the case if the inner
rel's parameterization is based on just one Var, but it could be
based on Vars from several relations, and then not only is the
inner loop reachable but it's wrongly coded.
Despite those errors, it still appears that the whole thing is
redundant given previous join_is_legal checks, so let's arrange
to only run it in assert-enabled builds.

Now that we have the sources for pg_bsd_indent in our code base these
are redundant.
It is now required to provide a list of files or directories to pgindent,
either by using --commit or on the command line. The equivalent of
previously running pgindent with no parameters is now `pgindent .`
Some extra checks are also added. duplicate files in the file list are
skipped, and there is a warning if no files are specified.
If the --commit option is used, the script now chdir's to the source
root, as git always reports files relative to that. (Fixes a gripe from

Here we fix a faulty "if" condition which failed to correctly handle two
or more consecutive NULL transition values when checking if the new value
is DISTINCT from the old value for presorted aggregates. Given a suitably
non-strict aggregate transition function, a byref aggregate could cause a
crash due to calling the type's equality function and passing along a
(Datum) 0 value to test for equality, the equality function would then try
to dereference that 0 Datum and segfault. For byval types, there'd have
been no crash and the equality function would have seen that the two 0
Datums matched, which (only by chance) meant the calling code would have
worked correctly.
Here we ensure that we only call the equality function when neither of
the input values are NULL.
This code is all new as of 1349d2790, so no backpatch needed.

When an aggregate function is used as a WindowFunc and a tuple transitions
out of the window frame, we ordinarily try to make use of the aggregate
function's inverse transition function to "unaggregate" the exiting tuple.
This optimization is disabled for various cases, including when the
aggregate contains a volatile function. In such a case we'd be unable to
ensure that the transition value was calculated to the same value during
transitions and inverse transitions. Unfortunately, we did this check by
calling contain_volatile_functions() which does not recursively search
SubPlans for volatile functions. If the aggregate function's arguments or
its FILTER clause contained a subplan with volatile functions then we'd
fail to notice this.
Here we fix this by just disabling the optimization when the WindowFunc
contains any subplans. Volatile functions are not the only reason that a
subplan may have nonrepeatable results.

This commit removes most of the Plan and Path nodes, which should never
be included in the query jumbling because we ignore these in Query
nodes. This is facilitated by making no_query_jumble an inherited
attribute, like no_copy, no_equal and no_read when the supertype of a
node is found as marked with that.
RawStmt is not used in parsed queries, so it can be removed from the
query jumbling. A couple of nodes defined in pathnodes.h, plannodes.h
and primnodes.h with NodeTag as supertype need to be marked
individually.
Forcing the execution of the query jumbling code with compute_query_id =
auto while pg_stat_statements is loaded brings the code coverage of
queryjumblefuncs.funcs.c to 95.6%.
The core code does not yet include a way to enforce the execution in
query jumbling except in pg_stat_statements, so the numbers I am
mentioning above will not reflect on the default coverage report with
just what is done in this commit.

Builds on 28e626bde00 and f30d62c2fc6. See the former for motivation.
Rows of the view show IO operations for a particular backend type, IO target
object, IO context combination (e.g. a client backend's operations on
permanent relations in shared buffers) and each column in the view is the
total number of IO Operations done (e.g. writes). So a cell in the view would
be, for example, the number of blocks of relation data written from shared
buffers by client backends since the last stats reset.
In anticipation of tracking WAL IO and non-block-oriented IO (such as
temporary file IO), the "op_bytes" column specifies the unit of the "reads",
"writes", and "extends" columns for a given row.
Rows for combinations of IO operation, backend type, target object and context
that never occur, are ommitted entirely. For example, checkpointer will never
operate on temporary relations.
Similarly, if an IO operation never occurs for such a combination, the IO
operation's cell will be null, to distinguish from 0 observed IO
operations. For example, bgwriter should not perform reads.
Note that some of the cells in the view are redundant with fields in
pg_stat_bgwriter (e.g. buffers_backend). For now, these have been kept for
backwards compatibility.

analyzejoins.c took care to clean out removed relids from the
clause_relids and required_relids of RestrictInfos associated with
the doomed rel ... but it paid no attention to the fact that if such a

containing similar fields.
I'm more than a bit surprised that this oversight hasn't caused

One of the add_nulling_relids calls in deconstruct_distribute_oj_quals
added an OJ relid to too few Vars, while the other added it to too
many. We should consider the syntactic structure not
min_left/righthand while deciding which Vars to decorate, and when
considering pushing up a lower outer join pursuant to transforming the
second form of OJ identity 3 to the first form, we only want to
decorate Vars coming from its LHS.
In a related bug, I realized that make_outerjoininfo was failing to
check a very basic property that's needed to apply OJ identity 3:
the syntactically-upper outer join clause can't refer to the lower
join's LHS. This didn't break the join order restriction logic,
but it led to setting bogus commute_xxx bits, possibly resulting
in bogus nullingrel markings in modified quals.

while reviewing the area for a different patch.

Commit 28e626bde00 introduced the infrastructure for tracking more detailed IO
statistics. This commit adds the actual collection of the new IO statistics
for relations and temporary relations. See aforementioned commit for goals and
high-level design.
The changes in this commit are fairly straight-forward. The bulk of the change
is to passing sufficient information to the callsites of pgstat_count_io_op().
A somewhat unsightly detail is that it currently is hard to find a better
place to count fsyncs than in md.c, whereas the other pgstat_count_io_op()
calls are in bufmgr.c/localbuf.c. As the number of fsyncs is tied to md.c
implementation details, it's not obvious there is a better answer.

This commit adds the infrastructure for more detailed IO statistics. The calls
to actually count IOs, a system view to access the new statistics,
documentation and tests will be added in subsequent commits, to make review
easier.
While we already had some IO statistics, e.g. in pg_stat_bgwriter and
pg_stat_database, they did not provide sufficient detail to understand what
the main sources of IO are, or whether configuration changes could avoid
IO. E.g., pg_stat_bgwriter.buffers_backend does contain the number of buffers
written out by a backend, but as that includes extending relations (always
done by backends) and writes triggered by the use of buffer access strategies,
it cannot easily be used to tune background writer or checkpointer. Similarly,
pg_stat_database.blks_read cannot easily be used to tune shared_buffers /
compute a cache hit ratio, as the use of buffer access strategies will often
prevent a large fraction of the read blocks to end up in shared_buffers.
The new IO statistics count IO operations (evict, extend, fsync, read, reuse,
and write), and are aggregated for each combination of backend type (backend,
autovacuum worker, bgwriter, etc), target object of the IO (relations, temp
relations) and context of the IO (normal, vacuum, bulkread, bulkwrite).
What is tracked in this series of patches, is sufficient to perform the
aforementioned analyses. Further details, e.g. tracking the number of buffer
hits, would make that even easier, but was left out for now, to keep the scope
of the already large patchset manageable.

While removing the use of SHM_QUEUE from predicate.c, in 96003717645, I made
two mistakes in GetSafeSnapshotBlockingPids():
- Removed the check for output_size
- Previously, when the first loop didn't find a matching proc, sxact would be
NULL. But with naive use of dlist_foreach() it ends up as the value of the
last iteration.
The second issue is the cause of occasional failures in the deadlock-hard and
deadlock-soft isolation tests that we have been observing on CI. The issue was
very hard to reproduce, as it requires the transactions.sql regression test to
run at the same time as the deadlock-{hard,soft} isolation test.

The DDLs like Refresh Materialized views that generate lots of temporary
data due to rewrite rules may not be processed by output plugins (for
example pgoutput). So, we won't send keep-alive messages for a long time
while processing such commands and that can lead the subscriber side to
timeout. We have previously fixed a similar case for large transactions in
commit f95d53eded where the output plugin filters all or most of the
changes but missed to handle the DDLs.
We decided not to backpatch this as this adds a new callback in the
existing exposed structure and moreover, users can increase the
wal_sender_timeout and wal_receiver_timeout to avoid this problem.

The logic for when to add the current outer join's own relid
to the nullingrels sets of output Vars and PHVs was overly
complicated and underly correct. Not sure why I didn't think
of this before, but since what we want is marking per the
syntactic structure, we can just consult our records about
the syntactic structure, ie syn_righthand/syn_lefthand.
Also, tighten the rule about when to add the commute_above_r
bits, in hopes of eliminating some squishy reasoning. I do not
know of a reason to think that that's broken as-is, but this way
seems better.
Per bug #17781 from Robins Tharakan.

Commit c3382a3c3, which moved the implementation of PG_TEST_EXTRA
from src/test/Makefile into individual test scripts, broke the
directions given in the subdirectory README files about how to run
these tests by hand. Update. Also mention wal_consistency_checking
in recovery/README --- that omission isn't the fault of c3382a3c3,
but it's still an omission.

The initial "put back OJ relids" adjustment of ojscope was
incorrect and unnecessary; it seems to be a leftover from
when I (tgl) was trying to get this function to work at all.
