No chance at all.  Breaking the connection between the data directory
and the postmaster.pid file means we don't have an interlock against
starting two postmasters in the same data directory.

I do not see the argument for moving the pid file anyway.  Surely no
one's going to tell us that the postmaster shouldn't have write access
to the data directory?
