I guess you are triyng to avoid the 'pg_dump - save_to_floppy -
walk_to_db2_place - pg_restore' pattern. Well, can you save `pg_dump' in
some middle place? One place which machine1 and machine2 have access to?
If so, you can kind of automate the job using two programs, one (in the
master) who 'upload' (via ftp maybe, scp or whatever) in this middle
place, ando other in the slave who 'download' and process the file using
pg_restore.
