Hi Michael.
Thx for info. I will check what PQcmdTuples is doing.

Yeap. Npgsql implements protocol itself. This is exactly the problem.
I'm not receiving the CompletedResponse protocol message when executing
the insert inside a function. It is through the CompletedResponse
postgresql server says how many rows were affected. But it seems that
when calling a function it doesn't return any.
