Yes! Exactly!

Shame on me. I've must read that page more times than I can remember. I
never realized that I could use the precision qualifier to do a cast (and
round):

comp_20031117=> create table ts (ts timestamp without time zone);
CREATE TABLE
comp_20031117=> insert into ts values ('2003-10-24 15:30:59.999');
INSERT 406299 1
comp_20031117=> select * from ts;
           ts
-------------------------
 2003-10-24 15:30:59.999
(1 row)

comp_20031117=> select to_char (ts ::timestamp(0), 'YYYYMMDDHH24MISS') from
ts;
    to_char
----------------
 20031024153100
(1 row)

thank you very much Joe

PS. Alvaro, your solution was what I was implementing already, but yes it's
ugly, that's why I gave it a second round. Thanks anyway.
