I know the guys around here use alternatives to the WEATHER program.  Unfortuna
tely, they're all at the AMS conference.  I'll forward your inquiry to them.

Sorry, I don't.

That is probably a good idea.

Because pqact(1) performs actions sequentially, it's not possible to simultaneo
usly write into a GDBM file (at least by the same pqact(1) process, so the "-cl
ose" option will be safe.  The question is whether or not closing and reopening
 GDBM files will incurr such an overhead as to reduce performance to the point 
where the pqact(1) process can't keep up.

I'm afraid the only way to tell is to try it.
