I I understand his need correctly, what is needed is a two-way sync:
changes in office 1 need to be in office 2 for when he goes to office
2, and then changes made at office 2 need to get sent back to office
1.  If I'm right, rserv won't work.  Recent discussions of
replication did not, IIRC, turn up any multi-master replication
systems other than Postgres-R.  (Maybe I don't RC, though.)

One answer might be to buy a laptop.  Carry the database in the
laptop.  It's another expense, of course, but it might work.

Alternatively, since the database can (presumably) be shut down every
night, why not shut down the postmaster at each end and use rsync to
synchronise the data directories?  (I haven't tested that, and don't
know if it'll work, but I think it should.)
