This implies that something someplace still has a link to the table with
that OID. You could do "\set VERBOSITY verbose" so that the code
location the error occurs at gets reported; that might be enough
information to guess what sort of thing is linking to the table.
Or you could just dig through the system catalogs looking for 4667548
in an OID column that links to pg_class.
