You haven't looked very hard then ;-). I expect this is because
pg_depend has links from the table to the constraints it owns.
You could probably remove the pg_depend entries to make it possible
to drop the table.
Use ALTER TABLE next time, eh? Hand manipulation of the system catalogs
is *not* for those who don't know exactly what they are doing.
