Pull Request as a puzzle piece of Issue #43902

Summary of Changes

Could not connect to the database. Connector returned error message: No such file or directory

See also my PR for the database framework: joomla-framework/database#310 . Would be good to know if the PR here still works with the changes from my framework PR.
