just the significant fields of FunctionCallInfoData, rather than MemSet'ing
the whole struct to zero.  Unused positions in the arg[] array will
thereby contain garbage rather than zeroes.  This buys back some of the
performance hit from increasing FUNC_MAX_ARGS.  Also tweak tuplesort.c
code for more speed by marking some routines 'inline'.  All together
these changes speed up simple sorts, like count(distinct int4column),
by about 25% on a P4 running RH Linux 7.2.

Good point. Thank you Masaru for the suggested fix.

Attached is a patch to fix the bug found by Masaru. His example now
produces:

regression=# SELECT * FROM connectby('connectby_tree', 'keyid',
'parent_keyid', '11', 0, '-') AS t(keyid int, parent_keyid int, level
int,
branch text);
  keyid | parent_keyid | level |  branch

-------+--------------+-------+----------
     11 |              |     0 | 11
     10 |           11 |     1 | 11-10
    111 |           11 |     1 | 11-111
      1 |          111 |     2 | 11-111-1
(4 rows)

While making the patch I also realized that the "no show branch" form of
the  function was not going to work very well for recursion detection.
Therefore  there is now a default branch delimiter ('~') that is used
internally, for  that case, to enable recursion detection to work. If
you need a different  delimiter for your specific data, you will have to
use the "show branch" form  of the function.

client
utilities (libpq.dll and psql.exe) for win32 (missing defines,
adjustments to
includes, pedantic casting, non-existent functions) per:
   http://developer.postgresql.org/docs/postgres/install-win32.html.

It compiles cleanly under Windows 2000 using Visual Studio .net. Also
compiles clean and passes all regression tests (regular and contrib)
under Linux.

In addition to a review by the usual suspects, it would be very
desirable for  someone well versed in the peculiarities of win32 to take
a look.

be able to do that, but the ability seems to have got lost in the
shuffle).  Add a -o nextOID switch for completeness.  Improve the
documentation to explain how and why to use these switches.

so that precision of result is always at least as good as you'd get from
float8 arithmetic (ie, always at least 16 digits of accuracy).  Per
pg_hackers discussion a few days ago.

Pass less-unsafe parameters to Darwin's NSLinkModule.  While this change prevents a backend coredump when loading a broken shlib, it also seems to suppress the error messages that might help debug the problem :-(.  Perhaps someone would like to supply a 'linkEdit' hook to get the best of both worlds.  But in the meantime, backend crash trumps error reporting.

remove the special case in ALTER DROP COLUMN to prohibit dropping a
table's last column.

Vacuum must not advance pg_database.datvacuumxid nor truncate CLOG
unless it's processed *all* tables in the database.  Vacuums run by
unprivileged users don't count.

(Beats head against nearest convenient wall...)

Please apply the patch attached and this should be solved.

heap_addheader is wrong because it doesn't cope with varlena fields,
notably indpred.

no reason to worry about the tuple commit status bits until the tuple
is inserted in a relation by heapam.c.  Also, improve comments for
heap_addheader().

at this area in the code.
