PostgreSQL is now supported (experimental)

We have successfully migrated the data to Postgres, but the installation of the php-pgsql extension fails. We think because the image is a non-root image.

debconf: DbDriver "passwords" warning: could not open /var/cache/debconf/passwords.dat: permission denied
...

Installing php-pgsql from here is a bit cumbersome and not the right way:

Command: >
      bash -c "echo 'debconf debconf/frontend select Noninteractive' | debconf-set-selections;
        apt-get update;
        apt-get install -y php-pgsql;
        /usr/bin/wait-for.sh -t 0 postgres:5432 -- /docker-entrypoint.sh"

To build a custom image is not a way we would like to go.

Adding php-psql in the official image by default is mentioned here: As a user I can run PostgreSQL in passbolt-ce-non-root container - #3 by AnatomicJC

What is the status of the implementation?

Thank you!
