The docstring incorrectly references Psycopg2Driver when this test is actually for the OracledbDriver. Please update the docstring to accurately reflect the driver being tested.

Suggested change

	"""Test the UDTF class builder in Psycopg2Driver using a real PostgreSQL connection"""
	"""Test the UDTF class builder in OracledbDriver using a real Oracle database connection"""
