pg_greentrunk provides fundamental components of GreenTrunk, an interface protocol (API) for using a PostgreSQL database with Python. It provides an interface for implementations to use, and provides documentation in the form of Python modules to allow immediate access to object descriptions, even when inside a Python console.
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.
pg_proboscis is a pure Python driver/interface for PostgreSQL. It is designed to give maximum flexibility to a user by providing protocol-level prepared statements and cursors. It features basic SSL support, COPY TO/FROM, automatic encoding/decoding of character data, and timestamp support regardless of the backend configuration(integer_datetimes).
