You're right. Using a JDBC connection pool to cache database connections, reuse physical
connections and minimize expensive operations in the creation and closing of database sessions
(1), or pgpool that is a connection pool server for PostgreSQL (2), the overhead of create a
server process for each new connection almost disappears.

It will only be necessary one connection pool for each database accessed, and pgpool will make a
new connection if there's no user name and database name pair yet.

Once more the middle tier simplifies the database operation.
