get_tables_to_repack() and get_all_vacuum_rels() were including other sessions' temporary tables in their output work list, causing REPACK, CLUSTER and VACUUM FULL (when executed without a table list) to attempt to acquire AccessExclusiveLock on them, potentially blocking for an extended time. Fix by skipping other-session temp tables early, before they are added to the list. This issue is ancient, but there have been no complaints about it that I know of, so I'm opting for not backpatching at present.
