Yeah, temp tables and plpgsql functions don't coexist very well yet.
(plpgsql tries to cache query plans, and at the moment there's no
mechanism to let it flush obsolete plans when a table is deleted.)

What you'll need to do is create a temp table that lasts for the whole
session and is re-used by each successive call of the plpgsql function.
You don't need to worry about dropping the temp table at session exit;
that's what temp tables are for, after all, to go away automatically.
So, just delete all its contents at entry or exit of the function,
and you can re-use it each time through.
