Possibly this item from the FAQ might help:

4.26) Why can't I reliably create/drop temporary tables in PL/PgSQL functions?

PL/PgSQL caches function contents, and an unfortunate side effect is that if a
PL/PgSQL function accesses a temporary table, and that table is later dropped
and recreated, and the function called again, the function will fail because
the cached function contents still point to the old temporary table. The
solution is to use EXECUTE for temporary table access in PL/PgSQL. This will
cause the query to be reparsed every time.
