Add session_role to postgresql modules (#43650)
* Allow session_role to be set for PostgreSQL By implementing session_role it becomes possible to run the specific PostgreSQL commands as a different role. The usecase that is immediately served by this, is the one that one ansible playbook can be shared by multiple users, which all have their own PostgreSQL login_user. They do not need to share login credentials, as they can share the role within the PostgreSQL database. The following example may give some insight: $ psql -U jdoe -X -d postgres postgres=> CREATE DATABASE abc; ERROR: permission denied to create database postgres=> set role postgres; SET postgres=# CREATE DATABASE abc; CREATE DATABASE fixes #43592 * Tests for session_role in PostgreSQL * Bump version_added for session_role feature * Remove explicit encrypted parameter from testspull/50373/head
