44.11. Environment Variables
Some of the environment variables that are accepted by the Python interpreter can also be used to affect PL/Python behavior. They would need to be set in the environment of the main PostgreSQL server process, for example in a start script. The available environment variables depend on the version of Python; see the Python documentation for details. At the time of this writing, the following environment variables have an affect on PL/Python, assuming an adequate Python version:
-
PYTHONHOME
-
PYTHONPATH
-
PYTHONY2K
-
PYTHONOPTIMIZE
-
PYTHONDEBUG
-
PYTHONVERBOSE
-
PYTHONCASEOK
-
PYTHONDONTWRITEBYTECODE
-
PYTHONIOENCODING
-
PYTHONUSERBASE
-
PYTHONHASHSEED
(It appears to be a Python implementation detail beyond the control
of PL/Python that some of the environment variables listed on
the
python
man page are only effective in a
command-line interpreter and not an embedded Python interpreter.)
