I just ran into this not that long ago. Instead of using ON COMMIT
DROP, use ON COMMIT DELETE ROWS that way the oid for the temp table
can be reused inside of pl/pgsql's cache. Tom pointed out that it
should be possible to hook up the new dependency system to the cache
and have the dependency delete expired items from the cache, but I
don't think anyone has the desire to add that at the moment. -sc
