Creating temp tables inside read only transactions

[mike beeper <mbeeper@xxxxxxxxxxx>]

I have a function that creates a temp table, populate it with results during intermediate processing, and reads from it at the end.  When the transaction is marked as read only, it does not allow creation of temp table, even though there are no permanent writes to the db.  Are there any workarounds? The following block errors out.

SET TRANSACTION ISOLATION LEVEL READ COMMITTED READ ONLY;
create temp table test(test int);
