However, a patch has emerged (thanks, Seneca!) that does allow it to
work, and which I'd expect to be portable (better still!).

We are still actively pursuing why it breaks, but supposing that still
remains outstanding, at least the following would allow AIX users to
better survive a build...

create circularity of role memberships.  This is a minimum-impact fix
for the problem reported by Florian Pflug.  I thought about removing
the superuser_arg test from is_member_of_role() altogether, as it seems
redundant for many of the callers --- but not all, and it's way too late
in the 8.1 cycle to be making large changes.  Perhaps reconsider this
later.

useful to do so.  This partially reverts an ill-considered search and
replace from a few months ago.

reporting of original column sources.

from a finished plan tree.  We have to copy the output column names
(resname fields) from the SubqueryScan down to its child plan node;
else, if this is the topmost level of the plan, the wrong column names
will be delivered to the client.  Per bug #2017 reported by Jolly Chen.

very narrow window in which SimpleLruReadPage or SimpleLruWritePage could

been assigned to another page).  This would result in an Assert failure if
Asserts were enabled, and probably in silent data corruption if not.

I intend a more extensive fix when 8.2 development starts, but this is a
reasonably low-impact patch for the existing branches.
