Why there is no records?

Hi,

draft=# SELECT n.nspname, c.oid FROM pg_constraint c, pg_namespace n
WHERE c.oid = n.oid AND c.conname = 'leagues_pkey';
nspname | oid
---------+-----
(0 rows)

draft=# SELECT * FROM pg_constraint WHERE conname = 'leagues_pkey';
oid | conname | connamespace | contype | condeferrable |
condeferred | convalidated | conrelid | contypid | conindid |
conparentid | confrelid | confupdtype | confdeltype | confmatchtype |
conislocal | coninhcount | connoinherit | conkey | confkey | conpfeqop
| conppeqop | conffeqop | confdelsetcols | conexclop | conbin
