Each table in your database has an entry in the pg_class table. Something like:
SELECT relallvisible from pg_class where oid = 'build.household'::regclass;
would show you the value, however, I think a problem here is unlikely
since that would just control the likelihood of an index-only-scan vs
an index-scan. You're getting a Seq-scan, which I imagine is going to
be quite a bit more expensive than even an index scan.
relallvisible has a value of 0 for that table on both databases.
