I'm running this as root so I assume that directory permissions are not
the issue. Funny you should mention attaching gdb as that is the other
thing that fails. If I try to attach it tells me something about
already debugging and then kills the PostgreSQL process when I exit gdb.
Note that gcore fails on -current as well. The gdb attach works fine
though. Unfortunately, so does PostgreSQL (it doesn't get into a busy
loop) so I can't use that to track down my PostgreSQL problem.
