No, I don't like that at all. Has race conditions against updates coming from the startup process. > Perhaps that indicates that field shouldn't be in pg_control, but in the > pid file? Yeah, that would be a different way to go at it. The postmaster would probably just write the state of the hot_standby GUC to the file, and pg_ctl would have to infer things from there. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
