   UPGRADE FUNCTIONS will remove OIDs from Slony-I tables in existing
   schemas, too.
 
+- When possible (based on log switching functionality), partial
+  indexes on sl_log_1 and sl_log_2 are created on a per-origin-node
+  basis.  This provides the performance boost of having an easily
+  recognizable index, but without the risk of having XIDs from
+  different nodes mixed together in one index, where rollover could
+  Cause Problems...
+
 These features are generally configurable, but the defaults ought to
 allow improved behaviour for all but the most "Extreme Uses."
