Mmy problem is freebsd getting totally loaded at which point it sends kills
to various processes. This sometime seems to end up with several actual
postmasters running, and none of them working.
Better existing process detection would help that greatly I'm sure.

I've been looking at the PID file creation mechanism we currently use.
It goes through a loop in an attempt to create the PID file, and if
one is there it attempts to remove it if the PID it contains no longer
exists (there are checks for shared memory usage as well).
This could be cleaned up rath

Shared memory in NetBSD is just an interface to mmap'd pages, so it can
be swapped to disk. But I assume your swap is not on NFS.

I would assume we'd add a test function like is_v6(inet). Given that,
you could add a check constraint "is_v6(col)" or "NOT is_v6(col)"
What about cases where I only want one or the other? Would a simple method
exist to limit input to v4 or v6 only?
Also, what are the implications to functions such as network_sub,
network_cmp, etc. when given mixed v4/v6 inputs as could easily happen if the
