You don't really need N users, unless you have more protection concerns
than you mentioned (like you want each database to have its own DBA with
no access to the other ones). A single "postgres" Unix userid can serve
for all the postmasters in typical cases. All you really need are a
separate data directory and a separate port number for each postmaster.
Pay attention though to the amount of machine resources you are
committing to each postmaster. You'd probably not want to push
shared_buffers up real far, for example.

TIP 4: Don't 'kill -9' the postmaster
