Another Data directory for second database - feasible?

I have a postgres installation with one database on a server. I'd need
to create another database; however, I'm curious if there's a way to
create the second database in a different directory than the existing
one. Is that feasible and how? Or does postgres only point to one data
directory? Thanks in advance.
