I would probably drop split and use tar :-)   It won't
compress (since openssl is in use) but it is able to split the
input and invoke scripts at the beginning end end of each
new medium.

You might consider adding a gzip step between the pg_dump
and the openssl.

If you come up with something useful please post it. I think
it's worthwhile to put into CVS or onto the Wiki.

Thanks,
