Dear Mr.: I want to exchange data in many DB (between one Central DB and many Remote DBs). The DBs are in individual LAN and not in WAN (INet), so they cannot transfer data directly. I can palce a host in INet. The DBs can access INet host and transfer data by the host. Now I want exctract data from WAL files in root/pg_xlog, but I don't understand its structure. How can I get it ? or who teach me please ? Thank you very much SunYanXiang sunyx@xxxxxxxxxx 2006-06-02
