Update test assertions for PostgreSQL command formatting in test_executor.py

- Adjusted assertions in test_actual_postgresql_start_unix and test_actual_postgresql_start_darwin to check for correct formatting of the `unix_socket_directories` parameter, ensuring consistency in command output.

These changes improve the accuracy of the tests related to PostgreSQL command execution.
