I want to do replication using WAL , please tell the methods by which log shipping is done ie moving the wal files to slaves and executing it.
Not possible at the moment: the log shipping facility that was introduced in 8.2 only lets you set up a so-called warm standby, which cannot be queried; it's not live replication. The warm standby system is a fairly crude hack that relies on WAL files being copied from the main server to the standby and then starting the standby in recovery mode when you want to bring it up. At this point the standby is your main database, and it can no longer WAL files. Documented here: http://www.postgresql.org/docs/8.2/static/warm-standby.html Alexander.
