I am writing function in postgres in python using the PL/Pythonu extension in postgres. I would like postgres to use my virutal environment (I am using virtualenv) instead of the global install. How do I go about doing this?
回答1:
As it turns out, one must add the path to where the libraries are found to the PYTHONPATH environment variable in postgres. Don't forget to quote your value eg:
PYTHONPATH='path to libraries'

tl;dr - exec activate_this.py inside plpython function will set python interpretor for the life of the postgresql session.
