This looks like corrupt data in pg_depend, specifically an entry or
entries with classid or refclassid = 297108, which should not happen
(the classid should always be the OID of one of a short list of system
catalogs).  You could try poking around in pg_depend to see if you
can identify any obviously-bogus rows.

No idea how it got that way.  Have you had any database crashes or the
like?
