OK
However the below does not work:
```
CREATE TABLE gpu_resources AS
SELECT * FROM madlib.gpu_configuration();
NOTICE: Table doesn't have 'DISTRIBUTED BY' clause. Creating a NULL policy entry.
ERROR: plpy.SPIError: function cannot execute on segment because it issues a non-SELECT statement (entry db 10.138.0.41:5432 pid=16886)
DETAIL:
Traceback (most recent call last):

with AOControl(False) and MinWarning("error"):
PL/Python function "gpu_configuration", line 154, in __enter__
PL/Python function "gpu_configuration"
SQL function "gpu_configuration" statement 1
```
I think this is a problem.
