2017-01-14Refs #16614 -- Prevented database errors from being masked by cursor close.François Freitag
When an error occurred during the cursor.execute statement, the cursor is closed. This operation did not fail with client-side cursors. Now, with server-side cursors, the close operation might fail (example below). The original error should be raised, not the one raised by cursor.close(), this is only clean-up code. For example, one can attempt to create a named cursor for an invalid query. psycopg will raise an error about the invalid query and the server-side cursor will not be created on PostgreSQL. When the code attempts to cursor.close(), it asks psycopg to close a cursor that was not created. pyscopg raises a new error: psycopg2.OperationalError: cursor "_django_curs_140365867840512_20" does not exist.
