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.
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.
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.
message that is reporting a prechecking error in a SQL function.
This is to cue client-side code that the syntax error position,
if any, is with respect to the function body and not the outer command.
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

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.
types. Update the regression tests and the documentation to reflect
this. Remove the UNSAFE_FLOATS #ifdef.
This is only half the story: we still unconditionally reject
floating point operations that result in +/- infinity. See
recent thread on -hackers for more information.
any amount of leading or trailing whitespace (where "whitespace"
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.
initialization of stats process under EXEC_BACKEND.
[A cleaner, rationalized approach to stat/backend/SSDataBase child
processes under EXEC_BACKEND is on my TODO list. However this patch
takes care of immediate concerns (ie. stats test now passes under
win32)]

support for 'week' within the date_trunc function.
Within the patch I added a couple of test cases and associated target
output, and changed the documentation to add 'week' appropriately.

Cygwin)

float8 types. This begins the deprecation of this feature: in 7.6,
this input will be rejected.
Also added a new error code for warnings about deprecated features,
and updated the regression tests.
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.

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.

junk emitted on the backend's stdout, but we should have the option to
catch possible worse errors in future.

the basic feature. Patch by Andrew Dunstan, some tweaking by Tom Lane.
Also, enable %option nodefault in these two lexers, and patch some gaps

and FreeDir routines modeled on the existing AllocateFile/FreeFile.
Like the latter, these routines will avoid failing on EMFILE/ENFILE
conditions whenever possible, and will prevent leakage of directory
descriptors if an elog() occurs while one is open.
Also, reduce PANIC to ERROR in MoveOfflineLogs() --- this is not
critical code and there is no reason to force a DB restart on failure.
All per recent trouble report from Olivier Hubaut.

logically belongs. Arrange to update the _NSGetArgv() copy of the argv

also have an _NSGetArgv() problem, but until we have some reports I'll
just make this #ifdef __darwin__.)
