the default target is 'install' instead of 'all'. So if you do a
make without target you actually do a make install, which is not
what one normally expects from a standard makefile.
ecpg.patch (wrong makefile expansion in some cases)
the ecpg Makefiles use a variable DESTDIR which is never defined
except by debian/rules makefile, in which case the ecpg makefiles
expand wrong pathnames. If we want to support a DESTDIR root it
must be done consistently in all the makefiles, not just in ecpg.

Suppress indexes on large objects from psql's \d listing;
they were confusing because the large object tables themselves are not
shown. (Besides, if you've got hundreds or thousands of large objects,
you really don't want to see 'em at all.)
Also, suppress all indexes from the \z ACL listing, since indexes have
no meaningful protection information.

Thanks for this, but SET TRANSACTION ISOLATION LEVEL
should be described like SET TIME ZONE: TO is not allowed, as well
as DEFAULT option. There are only two forms:
1. MyProc->xid assignment is moved to GetNewTransactionId so newer
transactions will not assume that MyProc transaction was committed
before snapshot calculations. With old MyProc->xid assignment
(in xact.c:StartTransaction()) there was ability to see the same
row twice (I used gdb for this)!...
2. Assignments of InvalidTransactionId to MyProc->xid and MyProc->xmin
are moved from xact.c:CommitTransaction() to
xact.c:RecordTransactionCommit() - this invalidation must be done
before releasing transaction locks or bad (too high) XmaxRecent value
might be used by vacuum ("ERROR: Child itemid marked as unused"
reported by "Hiroshi Inoue" <Inoue@tpf.co.jp>; once again, gdb
allowed me reproduce this error).

pg_dump failed on any database containing large objects,

on the LOs. How long has this been broken??
Make sure that only one intro is included in the integrated doc.
Multiple intros cause trouble since they have some section elements
(e.g. "y2k.sgml") in common leading to duplicate labels.
Include emacs formatting hints in the intro*.sgml sources.

Repair performance problem in SI segment manipulations: iterating
through MAXBACKENDS array entries used to be fine when MAXBACKENDS = 64.
It's not so cool with MAXBACKENDS = 1024 (or more!), especially not in a
frequently-used routine like SIDelExpiredDataEntries. Repair by making
procState array size be the soft MaxBackends limit rather than the hard
limit, and by converting SIGetProcStateLimit() to a macro.

When closure of the backend connection is detected during pqFlush,
do the right thing: look for a NOTICE message from the backend before we
close our side of the socket. 6.4 libpq did not reliably print the backend's

did the right thing if connection closure was detected during a read
