So... if your software isolates customers based on a "customer_id"
field in a table, how is that less secure than isolating a customer
based on the schema? Ie, you've just moved the customer_id field from
a column to part of the table name itself. One step up from that, what
keeps your software from selecting the wrong customer_id database name
too? See, it is all just *where* you put the distinguishing name...
For your resource question, having multiple DBs require each to have
its own handle within your app. When you have many simultaneous users,
you have lots and lots of file handles to manage. You want to minimize
the number of connections to the postgres server itself.
