I imagine that if you check the postmaster log you will notice a bleat near the beginning about failing to open the socket file (because of the pre-existence of the root-owned file). It would come up anyway as long as it could establish a TCP listen socket. Offhand I would guess that things got this way because of some errant tmp-cleaning script; perhaps the socket file got chown'd to root sometime in the past during the previous postmaster's life. regards, tom lane
