is done at creation time for plpgsql functions. Improve createlang and
droplang to support adding/dropping validators for PLs. Initial steps
towards producing a syntax error position from plpgsql syntax errors
(this part is a work in progress, and will change depending on outcome
of current discussions).

TID (heap position). This doesn't do anything to the validity of the
finished index, but by pretending to qsort() that there are no really
equal keys in the sort, we can avoid performance problems with qsort
implementations that have trouble with large numbers of equal keys.
Patch from Manfred Koizar.
so that the 'val' is computed only once, per recent discussion. The
speedup is not much when 'val' is just a simple variable, but could be
significant for larger expressions. More importantly this avoids issues
with multiple evaluations of a volatile 'val', and it allows the CASE
expression to be reverse-listed in its original form by ruleutils.c.
directly to the appropriate per-node execution function, using a function
pointer stored by ExecInitExpr. This speeds things up by eliminating one
level of function call. The function-pointer technique also enables further
small improvements such as only making one-time tests once (and then
changing the function pointer). Overall this seems to gain about 10%
on evaluation of simple expressions, which isn't earthshaking but seems
a worthwhile gain for a relatively small hack. Per recent discussion
on pghackers.
i've attached this again.
Additionally I include a small patch to remove mutex locking when a
DEFAULT/NULL connection is being retrieved. This is consistent with
libpq.

that by querying the environment explicitly first for LC_COLLATE and
LC_CTYPE. We have to do this because initdb passes those values in the
environment. If there is nothing there we fall back on the codepage.

implemented casts to varchar and bpchar using a cast-to-text function.
This is a holdover from before we had pg_cast; it now makes more sense
to just list these casts in pg_cast. While at it, add pg_cast entries
for the other direction (casts from varchar/bpchar) where feasible.

Looking at src/port/thread.c, line 189, it looks like somebody typo'd.
Looks like that second parameter should be "resultbuf", not "resbuf"?

In particular, don't depend on strtod() to accept 'NaN' and 'Infinity'
inputs (while this is required by C99, not all platforms are compliant
with that yet). Also, don't require glibc's behavior from isinf():
it seems that on a lot of platforms isinf() does not itself distinguish
between negative and positive infinity.

is defined by isspace()). This is for SQL conformance, as well
as consistency with other numeric types (e.g. oid, numeric).
Also refactor pg_atoi() to avoid looking at errno where not
necessary, and add a bunch of regression tests for the input
to these types.

Currently, src/interfaces/libpq/win32.mak builds a statically-linked
library "libpq.lib", a debug dll "libpq.dll", import library for the
debug dll "libpqdll.lib", a release dll "libpq.dll", import library for
the release dll "libpqdll.lib". To avoid naming clashes, I would make
the debug dll and import libraries "libpqd.dll" and "libpqddll.lib".
Basically, the debug build uses the cl flags: "/MDd /D _DEBUG", and the
release build uses the cl flags "/MD /D NDEBUG". Usually the debug
build has a "D" suffix on the file name, so for example:
libpqd.dll libpq, debug build
libpqd.lib libpq, debug build, import library
libpq.dll libpq, release build
libpq.lib libpq, release build, import library

equivalent sort expressions to use was broken: you can't just look
at the relation membership, you have to actually grovel over the
individual Vars in each expression. I think this did work when it
was written, but it was broken by subsequent optimizations that made
join relations not propagate every single input variable upward.
Must find the Var that got propagated, not choose one at random.
Per bug report from Daniel O'Neill.
of which redundant clause to remove, it removes the more expensive one.
In simple scenarios the clauses will be like 'var = var' and there's
no difference, but we are now capable of considering cases where there
are sub-selects in the clauses, and it makes a BIG difference.
