Connect to the database using this DBProxy\'s module and the given
connect arguments.  If the arguments match an existing pool, the
connection will be returned from the pool\'s current thread-local
connection instance, or if there is no thread-local connection
instance it will be checked out from the set of pooled connections.
If the pool has no available connections and allows new connections
to be created, a new database connection will be made.'
