this a test for specific AIX versions, but I don't know which ones need it.

we are not holding a buffer content lock; where it was, InterruptHoldoffCount
is positive and so we'd not respond to cancel signals as intended.  Also
add missing vacuum_delay_point() call in btvacuumcleanup.  This should fix

in a timely fashion (bug #2257).

is set.

option state hasn't been fully set up.  This is possible via PQreset()
and might occur in other code paths too, so a state flag seems the
most robust solution.  Per report from Arturs Zoldners.

not just some of them.

don't promise more than the code actually delivers.

Var referencing the subselect output.  While this case could possibly be made
to work, it seems not worth expending effort on.  Per report from Magnus
Naeslund(f).

French uses "" for "don't want".  Seems we have to keep the existing
behavior.

id (CVE-2006-0553).  Also fix related bug in SET SESSION AUTHORIZATION that
allows unprivileged users to crash the server, if it has been compiled with
Asserts enabled.  The escalation-of-privilege risk exists only in 8.1.0-8.1.2.
However, the Assert-crash risk exists in all releases back to 7.3.
Thanks to Akio Ishida for reporting this problem.

Latin1, like we do for other Latin encodings.

Back out patch pending review.

  While playing with this patch under 8.1.2 at home I discovered a
  mistake in how I manually applied one of the hunks to fe-auth.c.
  Basically, the base code had changed and so the patch needed to be
  modified slightly.  This is because the code no longer either has a
  freeable pointer under 'name' or has 'name' as NULL.

  The attached patch correctly frees the string from pg_krb5_authname
  (where it had been strdup'd) if and only if pg_krb5_authname returned
  a string (as opposed to falling through and having name be set using
  name = pw->name;).  Also added a comment to this effect.
  Please review.

I looked into this and it seems the problem is that the view doesn't
get flattened into the main query because of the has_nullable_targetlist
limitation in prepjointree.c.  That's triggered because pg_roles has
        '********'::text AS rolpassword
which isn't nullable, meaning it would produce wrong behavior if
referenced above the outer join.

Ultimately, the reason this is a problem is that the planner deals only
in simple Vars while processing joins; it doesn't want to think about
expressions.  I'm starting to think that it may be time to fix this,
because I've run into several related restrictions lately, but it seems
like a nontrivial project.

In the meantime, reducing the LEFT JOIN to pg_roles to a JOIN as per
Peter's suggestion seems like the best short-term workaround.

Ok, so *that's* where the bit about the query plan being simple enough.
Based on that, ISTM that it should be premissable for us to decide that
a cursor requiring a sort isn't "simple enough" to support SCROLL.

In any case, here's a patch that makes the non-standard behavior easier
for people to find.

--enable-depend it often tries to create the .deps directory twice and
bails out when it already exists due to a race condition of if doesn't
exist, then create.  This patch prevents mkdir from returning an error.
