Hi

I am trying to start bgworker from bgworker and create communication between these process. I have a code based on test_shm_mq. This code fails because BackendPidGetProc doesn't find related bgworker process, although the registrant process is living

registrant = BackendPidGetProc(MyBgworkerEntry->bgw_notify_pid)

Is expected behave?

Regards

Pavel
