Yeah, pretend it's an array with indexes 0,1.

regression=# create table p (f1 point);
CREATE TABLE
regression=# insert into p values('(12,34)');
INSERT 437746 1
regression=# select f1[0] from p;f1
----12
(1 row)

regression=# select f1[1] from p;f1
----34
(1 row)

regression=# update p set f1[1] = 55;
UPDATE 1
regression=# select * from p;  f1
---------(12,55)
(1 row)

regression=#
