| 965 | + Some of the environment variables that are accepted by the Python |
| 966 | + interpreter can also be used to affect PL/Python behavior. They |
| 967 | + would need to be set in the environment of the main PostgreSQL |
| 968 | + server process, for example in a start script. The available |
| 969 | + environment variables depend on the version of Python; see the |
| 970 | + Python documentation for details. At the time of this writing, the |
| 971 | + following environment variables have an affect on PL/Python, |
| 972 | + assuming an adequate Python version: |
