python3-testing.postgresql binary package in Ubuntu Focal arm64

 The testing.* Python modules provide a framework for Python unit test suites
 that need to run tests against servers, like network-based DBMSs.
 .
 testing.postgresql contains helper classes to work with a temporary
 PostgreSQL server. It automatically sets up a PostgreSQL instance in a
 temporary directory, and destroys it after testing.
 .
