I have the same problem with this guy.

http://archives.postgresql.org/pgsql-admin/2003-12/msg00205.php

>>I have a postgresql server process each running in my
>>desktop and the laptop.

>>Both servers have a database called MG with exactly
>>same scheme/layout. Now I enter the data in to similar
>>tables but at differing times.

>>I generally keep the primary keys seperate so that
>>they don't clash with each other. eg: oddnumber pkey
>>for laptop and even number for desktop.

>>Now how do I syncronize the data between the desktop
>>and laptop cleanly!

>>Any advise would be greatly appreciated.

>>DESK:ADDRESS ----- LAP:ADDRESS
>>DESK:TO_DO ----- LAP:TO_DO

>>DESK uses pkeys like 1001... for inserts
>>LAP uses pkeys like 2001... for inserts

>>I need both update for the modified records and insert
>>for new records. But how do I :-( ..

>>etc...

>>Thanks
