[ shrug... ] If you create an ON COMMIT DELETE temp table, you
are explicitly asking for a truncation to happen at every commit.
I don't think you have much room to beef about the fact that one
happens.
Maybe you could merge some of these tables (adding an additional
key column, probably) so that a single truncate suffices for all?
