+Gotchas
+=======
+
+Adding/renaming databases
+-------------------------
+
+List of databases used for filtering (OID-s are fetched from master on client connect) is only read on Walbouncer startup so to make sure the new/renamed
+database will be filtered out on the replica, you need to stop the replica and the Walbouncer, adjust the Walbouncer config, issue the CREATE/RENAME
+command, start Walbouncer and the replica. See above PDF for more details.
+
+Dropping databases
+------------------
+
+Have all slaves that want to filter out the dropped database actively streaming before you execute the drop. 
+Otherwise the slaves will not know to skip the drop record and xlog replay will fail with an error.
+
+
 Potential future features
 =========================
 
 - Also provide filtering for pg_basebackup.
 - Provide quorum for synchronous replication. (k of n servers have the data)
-- Create a protocol to use multicast to stream data.
