If so, that would probably explain the pattern I'm seeing in the dump of many updates of the pg_class row. This still doesn't give us a hint why the row disappeared, but maybe we can try running these functions for awhile and see if anyone can reproduce a failure. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
