da5f1dd722 Revise union_planner and associated routines to clean up breakage 
from EXCEPT/HAVING patch.  Cases involving nontrivial GROUP BY expressions
now work again.  Also, the code is at least somewhat better documented...

605d84941d Clean up cost_sort some more: most callers were double-counting 
the cost of reading the source data.

87d95ca04d Arrange for VACUUM to delete the init file that relcache.c uses 
to save a little bit of backend startup time.  This way, the first
backend started after a VACUUM will rebuild the init file with up-to-date
statistics for the critical system indexes.

c422e1a93d Fix compile failures in dt.c --- line broken in middle of 
an identifier :-(.  Sloppy transmission of a patch, likely.

17dbeebb5f Fill in reasonable-looking cost estimates in inserted nodes. 
This makes no difference to the optimizer, which has already decided what
it's gonna do, but it makes the output of EXPLAIN much more plausible.

7a7ba33536 Clean up some bogosities in path cost estimation, like 
sometimes estimating an index scan of a table to be cheaper than a
sequential scan of the same tuples...

11a0027e28 Fix nasty little typo that prevented get_cheapest_path_for_joinkeys 
from ever returning a path.  This put a bit of a crimp in the system's
ability to generate intelligent merge-join plans...

99f61dac7e Defend against 'update oid'. Someday we might want to support 
that, but it'd be a New Feature, wouldn't it ... in the meantime,
avoiding a backend crash seems worthwhile.

970583ab4f Several routines in setrefs.c would crash on array refs 
due to lack of check for recursing into a null subexpression.

26db818710 It looks like the multibyte regress tests only work if both 
the database encoding and the client encoding match the encoding expected
by the test.  So, force both of them to be set from the MULTIBYTE
environment var.  This allows regress tests to be run successfully in
multibyte environments other than the compiled-in default.

22fe451c9d psql's recognition of comments didn't work right in MULTIBYTE

0d99c95388 Correct potential infinite loop in pg_utf2wchar_with_len; 
it failed to cover the case where high bits of char are 100 or 101.
Not sure if fix is right, but it agrees with pg_utf_mblen ... and it
doesn't lock up ...

2acfc4f6b4 Multibyte tests were all 'failing' because of change of 
wording of 'relation does not exist' error message.  Update expected files
accordingly.

95cc41b81d Revise backend libpq interfaces so that messages to the frontend 
can be generated in a buffer and then sent to the frontend in a single
libpq call.  This solves problems with NOTICE and ERROR messages generated
in the middle of a data message or COPY OUT operation.

pg_proc entries for array I/O routines besides the one detected by the
original patcher.  Tighten type_sanity regress test accordingly.

09c5e84072 Change elog(ERROR) to get back to main loop via a plain sigsetjmp, 
instead of doing a kill(self, SIGQUIT) and expecting the signal handler
to do it.  Also, clean up inconsistent definitions of the sigjmp buffer
in the several files that already referenced it.

d30e2ac306 Portability patches for HPUX 11 and Unixware in configure 
and related files.  Also remove float.c's gratuitous redeclaration of
isinf() ... looks like there are more decls in there that ought to be
in config.h, but I'll leave well enough alone for now ...

a58843b49a Fix problems seen when result of a subselect was used in an 
expression context (ie, not at the top level of a WHERE clause).  Examples
like this one work now:

(value/(SELECT AVG(value) FROM t1 WHERE name = touter.name)) > 0.75;

This fixes a few of the problems Hiroshi Inoue complained of, but
I have not touched the rewrite-related issues.
