[GENERAL] Query optimization question

Which is faster? This...

SELECT t1.name
FROM t1, t2, t3, t4
WHERE
t1.id = 1 AND
t2.id = 2 AND
t3.id = 3 AND
t3.id = t4.id;

...or this...

SELECT t1.name
FROM t1, t2, t3, t4
WHERE
t1.id = 1 AND
t3.id = t4.id AND
t2.id = 2 AND
t3.id = 3;

Does it make a difference in pgsql?
