So then you'd need a restart for it to happen? As for launching it from the startup process I don't know, that might be a viable path. The code specifically explains why it's not possible to launch it from the postmaster, but I don't see anything that would make it impossible from the startup process. -- Magnus Hagander Me: https://www.hagander.net/ <http://www.hagander.net/> Work: https://www.redpill-linpro.com/ <http://www.redpill-linpro.com/>
