I think it has to be pg_depend, because there'd be no reason to
be calling getObjectClass() on a entry from one of those other
catalogs during a DROP TABLE.

So my thoughts are now turning towards there being corruption
in pg_depend's indexes as well as the heap. Try doing the above
query after turning enable_indexscan and enable_bitmapscan off.
