Revise plpgsql's scanner to process comments and string literals in a way
more nearly matching the core SQL scanner. The user-visible effects are:
* Block comments (slash-star comments) now nest, as per SQL spec.
* In standard_conforming_strings mode, backslash as the last character of a
non-E string literal is now correctly taken as an ordinary character;
formerly it was misinterpreted as escaping the ending quote. (Since the
string also had to pass through the core scanner, this invariably led
to syntax errors.)
* Formerly, backslashes in the format string of RAISE were always treated as
quoting the next character, regardless of mode. Now, they are ordinary
characters with standard_conforming_strings on, while with it off, they
introduce the same set of escapes as in the core SQL scanner. Also,
escape_string_warning is now effective for RAISE format strings. These
changes make RAISE format strings work just like any other string literal.
This is implemented by copying and pasting a lot of logic from the core
scanner. It would be a good idea to look into getting rid of plpgsql's
scanner entirely in favor of using the core scanner. However, that involves
more change than I can justify making during beta --- in particular, the core
scanner would have to become re-entrant.
In passing, remove the kluge that made the plpgsql scanner emit T_FUNCTION or
T_TRIGGER as a made-up first token. That presumably had some value once upon
a time, but now it's just useless complication for both the scanner and the
grammar.

unique1 = 42 in each relation scan. This had been broken by my patch of

less incorrect approach. That patch was meant to prevent incorrect extraction
of OR'd indexclauses from OR conditions above an outer join. To do that
correctly we need more information than the outerjoin_delay flag can provide,
so add a nullable_relids field to RestrictInfo that records exactly which
relations are nulled by outer joins that are underneath a particular qual
clause. A side benefit is that we can make the test in create_or_index_quals
more specific: it is now smart enough to extract an OR'd indexclause into the
outer side of an outer join, even though it must not do so in the inner side.

Fix the plpgsql memory leak exhibited in bug #4677. That leak was introduced
by my patch of 2007-01-28 to use per-subtransaction ExprContexts/EStates:
since we re-prepared any expression tree when the current subtransaction ID
changed, we'd accumulate more and more leaked expression state trees in the
outermost subtransaction if the same function was executed at multiple levels
of subtransaction nesting. To fix, go back to the previous scheme where
there was only one EState per transaction for simple plpgsql expressions.
We really only need an ExprContext per subtransaction, not a whole EState,
so it's possible to keep prepared expression state trees in the one EState
throughout the transaction. This should be more efficient as well as not
leaking memory for cases involving lots of subtransactions.
The added regression test is the case that inspired the 2007-01-28 patch in
the first place, just to make sure we didn't go backwards. The current
memory leak complaint is unfortunately hard to test for in the regression
test framework, though manual testing shows it's fixed.

Make \dt \di and friends more consistent about the treatment of
TOAST tables and indexes; to wit, never show either. (You can
examine them with plain \d if you're really so inclined.)

Minor wordsmithing on descriptions of some \d commands.

Use (unsigned char) cast in argument of pg_tolower(). Maybe it works on
Windows without that, but we shouldn't put bad examples where people might
copy them. Also, reformat slightly to improve the odds that pgindent
won't go nuts on this.

Add a comment documenting the question of whether PrefetchBuffer should
try to protect an already-existing buffer from being evicted. This was
left as an open issue when the posix_fadvise patch was committed. I'm
not sure there's any evidence to justify more work in this area, but we
should have some record about it in the source code.

Defend against possible crash if a plpython function does not specify names
for its arguments. Also add a regression test, since someone apparently
changed every single plpython test case to use only named parameters; else
we'd have noticed this sooner.

Make directory name comparisons on Win32 case insensitive.
This method will not catch all different ways since the locale
handling in NTFS doesn't provide an easy way to do that, but it
will hopefully solve the most common cases causing startup
problems when the backend is found in the system PATH.

Document that Solaris can't use effective_io_concurrency because of an
ineffective posix_fadvise().

Refactor ExecProject and associated routines so that fast-path code is used
for simple Var targetlist entries all the time, even when there are other
entries that are not simple Vars. Also, ensure that we prefetch attributes
(with slot_getsomeattrs) for all Vars in the targetlist, even those buried
within expressions. In combination these changes seem to significantly
reduce the runtime for cases where tlists are mostly but not exclusively
Vars. Per my proposal of yesterday.
