behavior of concurrent commands in cases where rows are being added and
removed from matching query criteria.

Minor word-smithing.

unnecessary thread address output parameter, to make this code look more
like that in pg_restore.

In passing, editorialize a bit on the description of the SQL:2008

Back-patch to 8.2; prior versions don't have the problem, at least not in
the reported case, because they don't try to recognize INTO in non-SELECT
statements.  (IOW, this is really fallout from the RETURNING patch.)

post-data step is run in a separate worker child (a thread on Windows, a child
process elsewhere) up to the concurrent number specified by the new pg_restore
command-line --multi-thread | -m switch.

qualifier, and add support for this in pg_dump.

This allows TOAST tables to have user-defined fillfactor, and will also
enable us to move the autovacuum parameters to reloptions without taking
away the possibility of setting values for TOAST tables.

It's missing in older versions too, but it doesn't seem worth
back-porting. All negative are just harmlessly treated as "no limit", and
tightening the check might even brake an application that relies on it.

encoding conversion functions.  These are not can't-happen cases because
it's possible to create a conversion with the wrong conversion function
for the specified encoding pair.  That would lead to an Assert crash in
an Assert-enabled build, or incorrect conversion otherwise, neither of
which is desirable.  This would be a DOS issue if production databases
were customarily built with asserts enabled, but fortunately that's not so.
Per an observation by Heikki.

Back-patch to all supported branches.

Per Tommy Gildseth <tommy.gildseth@usit.uio.no> report

Backpatch only for 8.3 because previous versions haven't such layer.

it's implemented, but accepted too much/too little compared to
the API documentation.

refactor the relcache code that used to do that.  This allows other callers
(particularly autovacuum) to do the same without necessarily having to open
and lock a table.
