Hi,
draft=# SELECT n.nspname, c.oid FROM pg_constraint c, pg_namespace n
WHERE c.oid = n.oid AND c.conname = 'leagues_pkey';
Because you are doing:
c.oid = n.oid
which is comparing the pg_constraint.oid to the pg_namespace.oid which
are not the same thing.
You need:
c.connamespace = n.oid
nspname | oid

draft=# SELECT * FROM pg_constraint WHERE conname = 'leagues_pkey';
oid | conname | connamespace | contype | condeferrable |
