Detailed Description

PostgreSQL database class with simplified access to libpq++.

Provide easy-to-use database access to PostgreSQL via libpqxx. The PQDB objects represent not the database, but a single connection to an existing database. Multiple PQDB objects can be instantiated, and each one will create a unique connection to the back-end database.
