You can drop it whenever you want.  If not, it drops on session exit.

On issue with plpgsql is that when you create a temp table in a function
and drop it, then call the function again, it still think the original
temp table exists.  You need to use EXECUTE in plpgsql if you want to
drop/create temp tables multiple times in the same session.
