PostgreSQL doesn't really offer much in the way of features for per-user
resource control, resource impact isolation, etc.
You can potentially run different PostgreSQL instances (postmasters, not
just databases) in different domains of a virtualization or
resource-control setup, but that's pretty inefficient, adds a lot of
admin work, and doesn't help if your users need to be able to use the
same database(s).
If you need strong user resource limits, user storage limits, etc
PostgreSQL might not be your best option. There are some things you can
do, but there's not much.
