fix_wal_skipping_bug_0118.patch (text/x-patch) patch

Hi,

Since I had tweaked wal-skipping logic for SR before,
there were two additional changes about that;
http://archives.postgresql.org/pgsql-committers/2009-11/msg00018.php
http://archives.postgresql.org/pgsql-committers/2009-12/msg00167.php

The attached patch deals with those changes.

Also I found that XLogStandbyInfoActive() should use
XLogIsNeeded() instead of XLogArchivingMode. The patch
also does that.

Regards,
