Hmm. Surely I did'nt make myself clear, PhpPgAdmin is not a problm here.
The problem is user A is owner of databses X1,Y1 Z1
user B is owner of databases X2,Yé,Z2
both users can see the the others DB. by doing a simple \l
It would be nice that unless a user is superuser he could'nt see databases
that are not his.
BTW how can I change ownership of databases and tables easealy?
