pg_class.relname stores only the relation name; if you want the
schema name then join pg_class.relnamespace and pg_namespace.oid
and refer to pg_namespace.nspname.  Another way would be to cast
'schemaname.relationname' to regclass and compare it to pg_class.oid:

SELECT ...
FROM pg_class c ...
WHERE c.oid = 'enumerations.eligibility_type'::regclass
  AND ...
