Time bug fixed?

There has been quite a few mails on the misoperation in date values before the epoc on RH7.3 and pgsql7.2.1.
Is this bug fixed? If yes: How can I achive this fix?
If not: How can I make postgresql work on RH7.3?

Shouldn't the FAQ mention the issue?

If some should be a bit confused: The error appears when operating on dates before the epoc:

rhklan=> create table test(day date);
CREATE
rhklan=> insert into test values('1969-2-2');
INSERT 824159 1
rhklan=> select age(now(),day) from test;
ERROR:  Unable to convert date to tm
