pg_dump should use very little space on the server, it just streams it
out to where ever you tell it.  You could run pg_dump on another host,
or do something like:

 pg_dump mydb | gzip | ssh otherbox "cat > out.sql.gz"

   Yes, from the other machine, run:

  [user@notmyhost ]$ pg_dump -h myhost -U mydbuser mydb > out.sql
