Instead of assigning the backend type in the Main function of each postmaster child, do it right after fork(), by which time it is already known by postmaster_child_launch(). This reduces the time frame during which MyBackendType is incorrect. Before this commit, ProcessStartupPacket would overwrite MyBackendType to B_BACKEND for dead-end backends, which is quite dubious. Stop that. We may now see MyBackendType == B_BG_WORKER before setting up MyBgworkerEntry. As far as I can see this is only a problem if we try to log a message and %b is in log_line_prefix, so we now have a constant string to cover that case. Previously, it would print "unrecognized", which seems strictly worse. Author: Euler Taveira <euler@eulerto.com> Discussion: https://postgr.es/m/e85c6671-1600-4112-8887-f97a8a5d07b2@app.fastmail.com
