Assuming you created a table like so:

smarlowe=# create table test (id serial,info text);
NOTICE:  CREATE TABLE will create implicit sequence "test_id_seq" for
serial column "test.id"
CREATE TABLE

Then use returning:

smarlowe=# insert into test (info) values ('this is a test') returning id;
 id
----
  1
(1 row)
