A temp table is only accessible to the owning process, so if you're hoping
for vacuuming of it to happen silently in background, you'll be sadly
disappointed.  The speed advantage of a temp table come exactly from not
having to worry about concurrent access, so this isn't a tradeoff that can
easily be adjusted.
