Yes, I think so. Rough design...
integrated_user_processes = 'x, y, z'
would run x(), y() and z() in their own processes. These would execute
after startup, or at consistent point in recovery. The code for these
would come from preload_libraries etc.
They would not block smart shutdown, though their shudown sequence might
delay it. User code would be executed last at startup and first thing at
shutdown.
API would be user_process_startup(), user_process_shutdown().

so it should be a GUC, that is settable only at start time.
we need those integrated processes at all when in a standby server?
