But there are two kind of problems there. First related with big date
values. ok, bot big deal yet :), but the second is taking my attention : if
you put a time with 995 to 999 miliseconds, it's represented as 60seconds
instead of 59seconds and 995 to 999 miliseconds. I don't think it's alright,
because I've never seen a datetime with 60seconds value (60 seconds is
always the next minute, in my conception). I would like some light here, is
it just a psql problem to show datetime values or a internal datetime
storage problem?

New example:

bxs=# insert into test2 values(1, '2002-08-29 04:23:59.994');
INSERT 259868 1
bxs=# insert into test2 values(2, '2002-08-29 04:23:59.995');
INSERT 259869 1
bxs=# insert into test2 values(2, '2002-08-29 04:23:59.996');
INSERT 259870 1
bxs=# insert into test2 values(3, '2002-08-29 04:23:59.997');
INSERT 259871 1
bxs=# insert into test2 values(4, '2002-08-29 04:23:59.998');
INSERT 259872 1
bxs=# insert into test2 values(5, '2002-08-29 04:23:59.999');
INSERT 259873 1
bxs=# select * from test2;
 x |     apagar_menor_que
---+---------------------------
 1 | 2002-08-29 04:23:59.99-03
 2 | 2002-08-29 04:23:59.99-03
