Vacuuming temporary tables

Seems temporary tables can not be vacuumed. It is because vacuum.c does
a sequential scan of the pg_class table, rather than using the cache.
Should this be fixed?

test=> create temporary table test (x integer);
CREATE
test=> vacuum test;
NOTICE: Vacuum: table not found
VACUUM

Do they show up in psql with \d? I only ask because in 6.5.0, they don't,
but psql's been completely rewritten for 7.0.

No, they do not. I am fixing VACUUM for temporary tables now. The
reason they don't show up is because the cache is not used by psql to
fetch information. It goes right into pg_class, which has only the
pgtemp* name.
