Use option A), it's multi-user safe whereas the other method isn't.

I'm project lead for pgAdmin II (pgadmin.postgresql.org) so I'm probably a
bit biased :-) but the main server I run at work hosts about 12 databases
for interactive (VB) applications, PHP apps and also logs data from 3 PBXs.
Most of the databases have at least 10 tables in them (a couple have about
40) and I have some tables over 1.7 million rows. In short, PostgreSQL does
a great job for me and I use it wherever I can (incidently, I also have
Informix, MS-SQL & Unidata servers here which I could have used instead of
PostgreSQL).
