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): PL/Python function "gpu_configuration", line 21, in <module> 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.
