pg_pqueue is a Python package that provides
low-level PQ protocol classes for interacting with
a PostgreSQL database. It supports version 3.0 of
the protocol. The package also provides a basic
protocol transaction class. This class keeps the
state of the protocol in an interrupt safe manner,
and validates the integrity of the communication
as messages are received. In general, you probably
will never use this package directly, unless you
are writing a driver.
