Not too easy. Currently I have only windows machine with
Postgresql/cygwin. I use dial-up for accessing internet, which isn't
nice to use. I will try this if I find some free computer to install
postgresql/linux ;-)
Anyway I already gave up this kind of query, especially I can't use CVS
as production server (should I?)
