I would not integrate such functionality into pg_dump, since it is not
necessary.
A good thing though would be a little HOWTO on splitting and/or compressing 
pg_dump output.

The principle is:

backup:
mkfifo tapepipe
( gzip --fast -c < tapepipe | split -b512m - database.dump.gz. ) &
pg_dump -f tapepipe regression
rm tapepipe

restore:
createdb regression
cat database.dump.gz.* | gzip -cd | psql regression

Instead of gzip you could use a faster compressor like lzop, but you get the
idea :-)
