Forgive me if I'm wrong Bruce, but I thought the LOCAL option
was WRT session visbility, not lifetime. IOW, all TEMP tables
exist until dropped or until the end of session, not
transaction. And LOCAL vs. GLOBAL determines visibility in other
sessions. Wasn't the point of Gavin's patch for ON COMMIT DROP
that got bumped to 7.4 to have the DBMS drop TEMP tables at TX
commit?
