Hi,all expert of the postgresql.
I want to learn the kernel of postgresql. When I debug it with gdb, I come to a problem that I can't solve. In the BackendStartup() it forks a new child process. I can't trace into the new child process with attach. It say that Operation is not permitted.
I really need your help.
Thank you very much.
