richardh=# select * from ta;
 a |  b

 1 | aaa
 2 | bbb
 3 | ccc

richardh=# select * from tb;
 c |  d
---+-----
 1 | fff
 3 | ggg
(2 rows)

richardh=# SELECT a,b,c,d FROM (SELECT a,b FROM ta) AS one LEFT JOIN (SELECT 
c,d FROM tb) AS two ON a=c;
 a |  b  | c |  d
---+-----+---+-----
 1 | aaa | 1 | fff
