Short Description
Wrong formated date on the first day of the Daylight Saving time.

Long Description
Hi every body,

I find this problem using the following configuration:
$ uname -a
HP-UX arvipa B.10.20 A 9000/715 2003042439 two-user license
$ gcc -v
gcc version 2.95.2 19991024 (release)

PostGreSQL v 7.0.3

I use PostGreSQL to store some statistics. The weekend we switch from normal time (TZ=MET-1MET) to daylight saving time
(TZ=MET-1METDST),and when i read statistics from this W.E., I saw a dupplicate data. 
In fact the problem was only on the display. Please see the code bellow.

As you can see, 24 Mar 2001 is displayed twice.

Bye

Laurent

Sample Code
scheduling=# select to_char( jour, '<small>Day</small><br>DD Mon YYYY'), jour from backlog where jour>'2001-03-23';

It's common problem with this time in 7.0.x - already fixed in 7.1.

 Note: use quotation marks for non-format masks, it is faster.=20
En example:

    to_char( jour, '"<small>"Day"</small><br>"DD Mon YYYY')
