Of course I did, do you think I create results by editing them into my
email?

The script:

delete from t1;
insert into t1 values (1, 123, 'first record');
insert into t1 values (2, 456, 'second record');
insert into t1 values (3, 789, 'third record');
select * from t1;
update t1 set col2 = t1copy.col2, col3 = t1copy.col3
from t1 as t1copy
where t1.col1 = 1 and t1copy.col1 = 3;
select * from t1;
select version();

The output:

DELETE 3
INSERT 0 1
INSERT 0 1
INSERT 0 1
col1 | col2 | col3
------+------+---------------
1 | 123 | first record
2 | 456 | second record
3 | 789 | third record
(3 rows)

UPDATE 1
col1 | col2 | col3
------+------+---------------
2 | 456 | second record
3 | 789 | third record
1 | 789 | third record
(3 rows)

version
------------------------------------------------------------------------
PostgreSQL 8.1.9 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 4.0.3
(1 row)

And BTW, I also tried your UPDATE SET (salary, name) but that only
works on PG 8.2 and above. I don't see why my query would fail in
subsequent releases.
