Hi Tiff,
from what you say, it sounds that each user should have his or her own database.
Considering the other answers here already pointing out the difficulties, why don't you just create a database for each user with the same name as the username and grant him or her access to it.
So, basically like this:
postgres=# create role "userA" login;
CREATE ROLE
postgres=# create database "userA" owner "userA";
CREATE DATABASE
postgres=# create role "userB" login;
CREATE ROLE
postgres=# create database "userB" owner "userB";
CREATE DATABASE
When, say, "userB" goes away, his or her data will go the way all things do:
drop database "userB";
drop role "userB";
Or did I misunderstand you?
Cheers,
Paul
