Dear community, First of all, I am completely new on this mailing list. I have read tons of tutorials, but I can't find how to set up further thing.I know how to add database for each user, but how to achieve in Postgres 8.1 how big assigned database should be on server machine? For instance: I want that database cash for user1 occupies 500Mb disk space. database calendar for user2 occupies 100Mb etc... best regards, Nikola
