🔴 High importance

Issue: The use of 'prefix' in 'NamedTemporaryFile' is incorrect. The 'prefix' parameter is intended for the filename prefix, not the directory. This can lead to unexpected behavior or errors.

Fix: Use the 'dir' parameter of 'NamedTemporaryFile' to specify the directory for the temporary file.

🔴 High importance

Issue: The change from 'schema' to 'database' in the 'PostgresHook' instantiation is incorrect. The 'PostgresHook' class expects a 'schema' parameter, not 'database'. This could lead to runtime errors when trying to establish a connection.

Fix: Revert the parameter name back to 'schema' to ensure compatibility with the 'PostgresHook' class.
