tests.utils.sql.py: Add a dummy Postgresql to prevent import error
Before raising this MR, consider whether the following are required, and complete if so:

Description
This short MR fixes a small issue when unit tests are executed on an environment without postgres installed.
Without the fix, the Postgresql
var is not created so attempted imports would fail.
