With zero space left, it's unlikely to get far; I repeat my statement that moving postmaster.pid alone is a useless activity. (It would be an incredibly dangerous thing to do anyway, since dissociating postmaster.pid from the data directory it's supposed to protect would substantially degrade its trustworthiness as a lock file.) regards, tom lane
