Hello:

I'm using postgres 7.0.2. When I use date_part('day', date) sometimes I
get wrong values. Ie:
and date_part('day', '1999-3-28')=27

and date_part('day', '2000-3-26')=25

Is it a bug?

It is a problem evaluating day numbers around daylight savings time
transitions. Fixed (I believe) in the upcoming 7.1 release.
