Which way is "better" depends on your access patterns. PostgreSQL
doesn't support cross-database queries (except via functions like
dblink), so if you need to join tables in one database with tables
in another then you'll probably want make A, B, and C schemas in
the same database. But if A, B, and C have no relationship with
one another then you might want to isolate them as separate databases.
