a join with 3 tables never seems to work:

test=# create table a(a int);
CREATE
test=# create table b(a int);
CREATE
test=# create table c(a int);
CREATE
test=# insert into a values (1);
INSERT 23734 1
test=# insert into b values (1);
INSERT 23744 1
test=# insert into c values (1);
INSERT 23736 1
test=# select *
test-# from a, b, c
test-# where a.a = b.a AND
test-# b.a = c.a;
a | a | a
---+---+---
1 | 1 | 1
(1 row)
test=# select * from a natural inner join b natural inner join c;
pqReadData() -- backend closed the channel unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
