ALTER TABLE ... ADD COLUMN myoid int;
CREATE TEMP SEQUENCE myoidsequence;
UPDATE ... SET myoid=nextval('myoidsequence');

then do the usual

SELECT a.* FROM ... a, ... b WHERE a.something=b.something AND
a.myoid<b.myoid;

Dance and if you are done with it,
ALTER TABLE ... DROP COLUMN myoid;
DROP TEMP SEQUENCE myoidsequence;
