Inserts into my table started generating an error message (see below),

l# /usr/pkg/bin/pg_dump -s -U postgres
pg_dump: failed sanity check, parent table OID 16401 of pg_rewrite entry
OID 16403 not found

Is this recoverable without using a backup?

Looks like to me corrupted system catalog!

I guess when you dropped the table it didn't delete the record from pg_rewrite was not deleted when the parent table was dropped. So you can try doing something:

delete from pg_rewrite where oid = 16403;

And see if this can fix the problem..
