NOTICE:  CREATE TABLE/PRIMARY KEY will create implicit index 'a_pkey' for
table 'a'
CREATE
test=# create table b(id int references a);
NOTICE:  CREATE TABLE will create implicit trigger(s) for FOREIGN KEY
check(s)
CREATE
test=# insert into a values(45);
INSERT 34924 1
test=# insert into a values(43);
INSERT 34925 1
test=# insert into a values(34);
INSERT 34926 1
test=# select a.id, b.id from a left join b using(id);id | id 
----+----43 |   45 |   
(2 rows)

test=# select * from a;id 
----454334
(3 rows)

test=# select * from b;id

(0 rows)

test=# insert into b values(34);
INSERT 34927 1
test=# select a.id, b.id from a left join b using(id);id | id
