Arrange for client authentication to occur before we select a specific

always be available to connect to).  This also gets rid of a small security
shortcoming that was introduced in the original patch to eliminate the flat
authentication files: before, you could find out whether or not the requested
database existed even if you couldn't pass the authentication checks.

The changes needed to support this are mainly just to treat pg_authid and
pg_auth_members as nailed relations, so that we can read them without having
to be able to locate real pg_class entries for them.  This mechanism was

applying it to those catalogs too.

Since the current code doesn't have support for accessing toast tables before

anyway in the old "flatfiles" implementation.

14 years agoFix plpgsql's exec_eval_expr() to ensure it returns a sane type OID
Tom Lane [Wed, 14 Apr 2010 23:52:10 +0000 (23:52 +0000)]
Fix plpgsql's exec_eval_expr() to ensure it returns a sane type OID
even when the expression is a query that returns no rows.

So far as I can tell, the only caller that actually fails when a garbage
OID is returned is exec_stmt_case(), which is new in 8.4 --- in all other
cases, we might make a useless trip through casting logic, but we won't
fail since the isnull flag will be set.  Hence, backpatch only to 8.4,
just in case there are apps out there that aren't expecting an error to
be thrown if the query returns more or less than one column.  (Which seems
unlikely, since the error would be thrown if the query ever did return a
row; but it's possible there's some never-exercised code out there.)

14 years agoFix a problem introduced by my patch of 2010-01-12 that revised the way
Tom Lane [Wed, 14 Apr 2010 21:31:11 +0000 (21:31 +0000)]
Fix a problem introduced by my patch of 2010-01-12 that revised the way
relcache reload works.  In the patched code, a relcache entry in process of
being rebuilt doesn't get unhooked from the relcache hash table; which means
that if a cache flush occurs due to sinval queue overrun while we're
rebuilding it, the entry could get blown away by RelationCacheInvalidate,
resulting in crash or misbehavior.  Fix by ensuring that an entry being
rebuilt has positive refcount, so it won't be seen as a target for removal
if a cache flush occurs.  (This will mean that the entry gets rebuilt twice
in such a scenario, but that's okay.)  It appears that the problem can only
arise within a transaction that has previously reassigned the relfilenode of
a pre-existing table, via TRUNCATE or a similar operation.  Per bug #5412
from Rusty Conover.

Back-patch to 8.2, same as the patch that introduced the problem.
I think that the failure can't actually occur in 8.2, since it lacks the
rd_newRelfilenodeSubid optimization, but let's make it work like the later
branches anyway.
