Subject: [PATCH] Note explicitly that hash indexes are also not replicated
 because they're not WAL-logged. Make the notice about the lack of WAL-logging
 more visible by making it a <caution>. Also remove the false statement from
 hot standby caveats section that hash indexes are not used during hot
 standby.
