pyPgSQL is a package of two modules that provide a Python DB-API 2.0 compliant interface to PostgreSQL databases. The first module, libpq, exports the PostgreSQL C API to Python. This module is written in C and can be compiled into Python or can be dynamically loaded on demand. The second module, PgSQL, provides the DB-API 2.0 compliant interface and support for various PostgreSQL data types, such as INT8, NUMERIC, MONEY, BOOL, ARRAYS, etc. This module is written in Python.
