7.3 is *not* in shape for production use yet.  I too would recommend
using 7.2.1 over 7.1, but that won't help his problem.

Should work fine; I've seen people using hundreds of separate databases.
It's a tad wasteful of disk space (since each DB needs its own copy of
the basic system catalogs, at a meg or two each) but it works.  If you
want airtight separation between users, a DB per user will probably be
the preferred setup even in 7.3.
