use of the PL Python extension

[epa64]

Hi,
I am using a postgres:13.3-buster docker image with the debian postgresql-plpython3-13 package.

The extensions used are :

• plpython3u
• jsonb_plpython3u

Is it possible to add the Debian packages of python 3.7 and postgresql-plpython3-13 to the citusdata docker file?

I attach my dockerfile.
Dockerfile.txt

Best regards
Eric Papet
