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.

Per recent proposal to pghackers.

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.

queries without regard to whether coercions are stated explicitly or
implicitly.  Per suggestion from Stephan Szabo.

I think I have the fix for part of it, but this remains...

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.

taught about multi-screen-column kanji characters; Tatsuo has promised
to provide the needed infrastructure for that.

This is to cue client-side code that the syntax error position,

incompatible enough to prevent indexscanning the referenced table.  Also,
improve the error message that pops out when we can't implement the FK at
all for lack of a usable equality operator.  Fabien Coelho, with some review
by Tom Lane.

7.4 rewrite for hashed aggregate support.  If the transition data type
is pass-by-reference, the transValue must be pfreed when starting a new
group boundary, else we have a one-value-per-group leakage.  Thanks to
Rae Steining for providing a reproducible test case.

[ Note: int8-exp-three-digits.out needs the same treatment]

Will review recent changes for float4/8 and implications for win32 when
I get a chance.
