No. Only the session that created the temp table can vacuum it.
Autovacuum skips temp tables. I guess the only thing you can do here is
close that session.
I'm thinking that maybe should make vac_update_datfrozenxid ignore temp
tables. But this doesn't really work, because if we were to truncate
pg_clog there would be tuples on the temp table marked with XIDs that
are nowhere to be found. Maybe we could make some noise about it
This is a problem only in recent releases (8.2) because we started
allowing the max freeze age be configurable.
