Yes, this is a known bug. Two bugs actually, first being that the
trigger definitions don't track the rename (they should probably be
storing OID not relname, although that would complicate dump/restore).
Second is that the table opens in the triggers themselves neglect to
check for open failure :-(, which results in crashes later on.
