When setting up pagure using postgres along with pagure, I get getting warnings, even when pushing changes to a repository as shown,

Which one Is recommended to use on pagure along with postgres?
psycopg2 or psycopg2-binary ?

A workaround when using psycopg2 could be adding 

import warnings
warnings.filterwarnings("ignore", category=UserWarning, module='psycopg2')

to the hookrunner.
This cleans the output in case psycopg2 is the default.

This warning only applies when you're installing from PyPI. This is a non-issue for Pagure normally. We will maintain the requirement to be described as psycopg2, since that's the actual requirement.

If you install the distribution's psycopg2 module package and make you venv expose that, then the warning will go away.

Oh! I see that must be it.
I'll confirm, right now.

Thanks.

Indeed using the distribution version can solve the issue.
I see there are many options there,

  1. greping the system version and tell pip install that specific version (psyconpg==2.6.1).
  2. Use virtualenv --system-site-packages then install over it with pip -I (venv).
  3. Make a plain link
    ln -s ../system-site-package/psycopg2 venv/.../psycopg2

What would be the recommended approach?
Edited by ark74

Use --system-site-packages when creating the venv. pip will not install psycopg2 if it detects it already there from the distribution.

Thanks!
