Introduction

You may either choose to use the “classic” PyGreSQL interface provided by the pg module or else the newer DB-API 2.0 compliant interface provided by the pgdb module.

The following part of the documentation covers only the older pg API.

The pg module handles three types of objects,

  • the Connection instances, which handle the connection and all the requests to the database,
  • the LargeObject instances, which handle all the accesses to PostgreSQL large objects,
  • the Query instances that handle query results

and it provides a convenient wrapper class DB for the basic Connection class.
