I think that window would be acceptable. If not, then the way to deal with it would seem to be to create an entirely new mechanism to communicate with pg_ctl (e.g., a file) and call that at the very end of StartupXLOG(). I'm not sure that that is worth it. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
