As the Odoo Docker images are based on Debian Jessie and Stretch, they
use the postgresql-client package from the respective Debian repo.
The backup feature of Odoo uses the postgresql-client. As a consequence,
if a database server newer than the client is used, the backup may fail.
For example, when using the Odoo Docker image 10.0 against a postgresql
server 10.0, the backup fails.
With this commit, the latest postgresql-client is used from the Postgres
repository. As they seem to be backward compatible, the Odoo backup will
succeed wathever the client/server combination.
fixesodoo/odoo#30599
In Odoo, ldap, qrcode and vobject python modules are set as required in
odoo/setup.py. On the other hand, they are only recommendend in the
Debian package.
As a consequence, it was difficult to run some Odoo modules that
required one of them.
The Odoo Debian package was adapted in master where they were added as
dependencies in odoo/odoo@2ff49c5fcb .
With this commit, they are installed in the Docker images.
This is a part of the fix of odoo/odoo#27752.
