The diff looks so simple and easy. But to find it wasn't fun.
It must have been there for a long time. What happened:
When a tuple in one of some central catalogs was updated, the
referenced relation got flushed, so it would be reopened on
the next access (to reflect new triggers, rules and table
structure changes into the relation cache).
Some data (the tupleDescriptor e.g.) is used in the system
cache too. So when a relation is subject to the system cache,
this must know too that a cached system relation got flushed
because the tupleDesc data gets freed during the flush!
For the GRANT/REVOKE on pg_class it was slightly different.
There is some local data in inval.c that gets initialized on
the first invalidation of a tuple in some central catalogs.
This needs a SysCache lookup in pg_class. But when the first
of all commands is a GRANT on pg_class, exactly the needed
tuple is the one actually invalidated. So I added little code
snippets that the initialization of the local variables in
inval.c will already happen during InitPostgres().
Enclosed is the regression.diffs file from running the Feb 21st
snapshot regression tests for inclusion in src/test/regression
as regression.Aix41. Appears to be standard differences to me,
error messages, fp accuracy and times off by an hour due to PST
vs PDT.

For some reason, under FreeBSD, it appears that the mktemp() value needs the
extra 'X' to improve/ensure uniqueness
below is the patch to have views to override the permission
checks for the accessed tables. Now we can do the following:
CREATE VIEW db_user AS SELECT
usename,
usesysid,
usecreatedb,
usetrace,
usecatupd,
'**********'::text as passwd,
valuntil
FROM pg_user;
REVOKE ALL ON pg_user FROM public;
REVOKE ALL ON db_user FROM public;
GRANT SELECT ON db_user TO public;
any other, example program.
I have tracked this down to a call to PQfinish() in ECPGfinish()
that occurs before any connection is established.

from configure.in, and I don't know how to patch it to get a working
'configure'.

Missing port-protos.h (not needed, I think). Wants dld.h. Should
really use the system dl stuff (like i386_solaris). Needs to include
<netinet/in.h> before <arpa/inet.h>. Here are some patches...
compiler define that should have been enabled, but was not due to
different naming conventions for Linux/Alpha. Attached is the patch he
sent me, that I have not had a chance to test yet.

The file 'backend/utils/adt/arrayfuncs.c' won't compile with the
February 14th snapshot, because of an inconsistency between the
declaration and implementation of ReadArrayStr(). As far as I can
tell, the predeclaration is wrong. I assume this is what was meant:
just a little correction in the pltcl_guide.nr.
Sometimes I changed the name of tuple arguments to numbers
like the other args are. Otherwise it wasn't possible to
create a function as
CREATE FUNCTION f (EMP, EMP) ... LANGUAGE 'pltcl';
The arguments are now accessed in the function as
$1(name) vs. $2(name)
Only occurrs in
src/include/storage/s_lock.h:#if defined(__AIX)
src/include/utils/dt.h:#if defined(__AIX)
src/include/utils/nabstime.h:#if defined(__AIX)
Simply delete one underscore, only occurs once per file, so no patch.
Someone changed the parser to build a TypeName node on CREATE
FUNCTION in any case. As a side effect, ALL! functions
created got the proretset attribute to true. Thus for a
SELECT the parser wrapped an Iter node around the Expr and
since singleton functions set isDone the Iter returns no
tuple up.
Apart from this Makefile hack, all I've done is to make dynamically
loaded code modules fail properly (as was already done for __mips__,
although I think this is too loose: I believe NetBSD for the pmax can
do dynamic linking), and to add test-and-set lock handling. As Bruce
suggested, this is done in a maximally efficient inlined way: I was
not aware that this code was so important, speed-wise.

Calls to SS_replace_correlation_vars() and SS_process_sublinks() in

Get rid of #ifdef INDEXSCAN_PATCH in createplan.c.
ExecReScan for nodeAgg, nodeHash, nodeHashjoin, nodeNestloop and nodeResult.
Fixed ExecReScan for nodeMaterial.
Get rid of #ifdef INDEXSCAN_PATCH.
Get rid of ExecMarkPos and ExecRestrPos in nodeNestloop.
