Chapter 41. PL/Python - Python Procedural Language
The PL/Python procedural language allows
PostgreSQL functions to be written in the
Python language.
To install PL/Python in a particular database, use
createlang plpythonu dbname.
Tip: If a language is installed into template1, all subsequently
created databases will have the language installed automatically.
As of PostgreSQL 7.4, PL/Python is only
available as an "untrusted" language (meaning it does not
offer any way of restricting what users can do in it). It has
therefore been renamed to plpythonu. The trusted
variant plpython might become available again in future,
if a new secure execution mechanism is developed in Python.
Note: Users of source packages must specially enable the build of
PL/Python during the installation process. (Refer to the
installation instructions for more information.) Users of binary
packages might find PL/Python in a separate subpackage.
