My company has two locations: Head Quarters (HQ) and a sub location (SL).

Both locations (HQ and SL) has separate PostgreSQL databases with the same schema and they will do transactions (insert/delete/update) in off-line. When both comes on line, both databases need to be synchronized (ie, come in the same state). Is it possible?
