I think this already exists:
test=# select 'joe.foo'::regclass::oid;
oid
--------
125532
(1 row)
test=# select 'public.foo'::regclass::oid;
oid
--------
125475
(1 row)
test=# select 'foo'::regclass::oid;
oid
--------
125475
(1 row)
test=# select current_schema();
current_schema
----------------
public
(1 row)
