-     <para>
-      If decoding begins partway through a transaction that modifies
-      system catalogs, the decoder may not recognize that, causing it to
-      fail to treat that transaction as in-progress for catalog lookups.
-      This fix deals with the case that a top-level transaction is already
-      marked as containing catalog changes, but its subtransaction(s) are
-      not.
