Not as long as they aren't in the same data directory ;-). What Simon was wondering about was whether an archiver process had somehow been left over from a previous incarnation of the test postmaster. The thing to do is look through "ps auxww" (or local equivalent) and see if you see more than one thing calling itself an archiver process. (Whether or not this explains Jeff's problem, it definitely seems like a failure mode that we need to guard against. We go to great lengths to prevent a new postmaster from starting when there are still live backends from a previous postmaster, but I don't think that interlock is effective for the archiver.) regards, tom lane
