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...

function)

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.

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
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.

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.

Add README.CVS to help CVS folks find this information.

the way, fix a typo and make a few SGML cleanups.
