That's not going to accomplish a lot --- it'll only cause the session you did the SET in to report to the stats collector. You need to change them in postgresql.conf and SIGHUP the postmaster so that they'll take effect in all sessions. >>> If it's not running, look in the postmaster log right after >>> restarting the postmaster; there may be a message there about why >>> not. > I cannot restart the postmaster, it is a production server. [ shrug... ] If the stats collector isn't running, you aren't going to get it to run without a postmaster restart. But you didn't say what the ps output showed. regards, tom lane
