Greetings,
It looks like to_char is unable to convert dates that fall in the range
of 01/01/1902 to 12/31/1969 (see below). I am running the Postgresql RPM
that is distributed with RH 8.0 (7.2.2.1). PGDATESTYLE is set to "SQL".
I find to_char behaves correctly on my RH 7.2 box with Postgresql 7.2
compiled from source.
Are there any known workarounds, or should I try compiling 7.2.3 from
source on my RH 8 box?
