[ digs in CVS logs ... ] I think vacuumlo is actually entirely broken
in the 7.3 branch, because this 7.4 patch:

* contrib/vacuumlo/vacuumlo.c: Following patch avoids removing oids
in the temporary table from the temporary table.
Kenji Sugita
wasn't ever back-patched. The former coding was assuming that temp
tables had real names of the form "pg_temp_NNN", which is no longer
true in 7.3, and the net result would be that nothing got deleted.
There were some schema-awareness bugs too, but that one would render
the whole thing a no-op.
