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 :-)
