PostgreSQL PQ Protocol Modules
PQueue is a package providing low-level PQ protocol classes for interacting with a PostgreSQL database. It supports version 3.0 of the protocol–the current primary version of 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.
