Pass List* of Aggregs into executor, and create needed array there.
No longer need to double-processs Aggregs with second copy in Query.

Fix crash when doing:

	select sum(x+1) from test where 1 > 0;

tests running "as expected"...

it is (!isnan() && !finite()) instead

interfaces/{libpq,libpgtcl}

OK, here comes a patch, DBD::Pg (and possibly other 3rd party clients)
can connect to unix sockets.
Patch is against current source tree.

Background:
libpq set some policy for client, which it should not
IMHO. It prevent some 3rd party clients to connect with
unix domain sockets etc.

reference to the name of the shared library, instead of dereferencing
the definition from the top of the file.

==========================================
What follows is a set of diffs that cleans up the usage of BLCKSZ.

As a side effect, the person compiling the code can change the
value of BLCKSZ _at_their_own_risk_.  By that, I mean that I've
tried it here at 4096 and 16384 with no ill-effects.  A value
of 4096 _shouldn't_ affect much as far as the kernel/file system
goes, but making it bigger than 8192 can have severe consequences
if you don't know what you're doing.  16394 worked for me, _BUT_
when I went to 32768 and did an initdb, the SCSI driver broke and
the partition that I was running under went to hell in a hand
basket. Had to reboot and do a good bit of fsck'ing to fix things up.

The patch can be safely applied though.  Just leave BLCKSZ = 8192
and everything is as before.  It basically only cleans up all of the
references to BLCKSZ in the code.

If this patch is applied, a comment in the config.h file though above
the BLCKSZ define with warning about monkeying around with it would
be a good idea.

(Also cleans up some of the #includes in files referencing BLCKSZ.)

Some behavior of the triggers test cases changed for the least week or two;
 now back to the usual expected behavior.
