Re: Problems with "order by clause"

Erik,

I finally had a few minutes to try to reproduce you problem. However I
do not see the same behavior as you. I tested on 7.2.1 with the 7.2.1
jdbc driver on a database created in the C locale. I see the same order
in the output under jdbc as I do in psql.

tralala
tralal
Tralala

thanks,
