I tried that, and got a crash somewhere in the code that inherits the syslogger pipe/socket to the child process. I don't understand why, and I don't feel like debugging any deeper into that right now. If you or someone else wants to give it a shot, that would be good. If not, I might try again some other day after sleeping over it. Anyway, here's the patch I had in mind for back-branches. -- Heikki Linnakangas EnterpriseDB http://www.enterprisedb.com
