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.)
