No exceptions means your database operation worked fine.
result status is not an exception.
It means the information of frontend/backend protocal, after a SQL-statement
is execute.
The following is a list of backend IPC commands (v3)
----------------------------------------------------
Z - Zero / Ready for Query
[...]
For instance:
----------------------------------------------------
SELECT * FROM my_table;
The backend protocal should return T (Row Description) and the frontend
protocal should return Q (Query)
----------------------------------------------------
DROP TABLE my_table;
The backend protocal should return C (Complete) and the frontend protocal
should return Q (Query)
What are you testing, really? "Normal" Python code should use a
PostgreSQL DB-API module or a wrapper on top of it, like SQLAlchemy.
Generally, you shouldn't have to drop down to protocol-level functions,
unless you're developing a PostgreSQL adapter yourself.
Care to explain why you're messing around with this low-level functions?
