"""PyGreSQL classic interface.
This pg module implements some basic database management stuff.
It includes the _pg module and builds on it, providing the higher
level wrapper class named DB with additional functionality.
This is known as the "classic" ("old style") PyGreSQL interface.
For a DB-API 2 compliant interface use the newer pgdb module.
