SELECT pg_class.relname, pg_attribute.attname   FROM pg_class, pg_attribute, pg_index   WHERE pg_class.oid =
pg_attribute.attrelidAND       pg_class.oid = pg_index.indrelid AND       pg_index.indkey[0] = pg_attribute.attnum AND
    pg_index.indisprimary = 't'
 

Caveat:  Does not work for complex primary keys.
