Bug details

Describe the bug

We see that when we put version: 13 into the pillar we still see at Ubunut 20.04 LTS that also Postgresql-14 will be installed.

dpkg -l | grep postgres

ii pgdg-keyring 2018.2 all keyring for apt.postgresql.org
ii postgresql-13 13.7-1.pgdg20.04+1 amd64 The World's Most Advanced Open Source Relational Database
ii postgresql-14 14.3-1.pgdg20.04+1 amd64 The World's Most Advanced Open Source Relational Database
ii postgresql-client-13 13.7-1.pgdg20.04+1 amd64 front-end programs for PostgreSQL 13
ii postgresql-client-14 14.3-1.pgdg20.04+1 amd64 front-end programs for PostgreSQL 14
ii postgresql-client-common 241.pgdg20.04+1 all manager for multiple PostgreSQL client versions
ii postgresql-common 241.pgdg20.04+1 all PostgreSQL database-cluster manager
ii postgresql-contrib 14+241.pgdg20.04+1 all additional facilities for PostgreSQL (supported version)

Steps to reproduce the bug

salt-call state.sls postgres.server

Expected behaviour

We think dat de postgresql-repo must be used the version so OS do not install postgres-14 version

Attempts to fix the bug

You should could update the postgresql-repo with 'deb [signed-by=/usr/share/postgresql-common/pgdg/apt.postgresql.org.gpg] http://apt.postgresql.org/pub/repos/apt focal-pgdg main {version}'.
In this case this will be 13.
