Unlike some other databases, PostgreSQL doesn't deal with size limits.
Unless you really want to limit the size of each database there's
nothing to worry about. If you do want to limit the size, your only
option is to create a cluster for each user and let the OS quota limit
size (though many versions of PostgreSQL don't react too kindly to
running out of space).

A third option is to use one cluster, but create each database with it's
own tablespace, and only give users access to their tablespaces. It's
not quite as fool-proof as multiple clusters, but it's a lot easier on
system resources.
