If as you say access to the database is via a single application database
user, it will probably make more sense to use multiple schemas rather than
multiple databases. Keeping everything in one database will simplify
administration (e.g. making backups - ypu'll just need to dump the one database
rather than looping through a variable number) and will make life easier if you
ever need to do some kind of query involving multiple customers.
There will also be less overhead when adding a new schema vs adding
a new database.
