Correct, you should just drop the ones that aren't in pg_catalog.

That sure looks like a bug, but there's not enough info here to
diagnose. Is there actually a pg_toast.pg_toast_2147483647 table
in the 8.4 cluster? (I'm betting not.) Could you try extracting
a test case? I wonder whether "pg_dump -s" from the 8.4 database,
loaded into a fresh 8.4 database, would be enough to reproduce.
