+    <command>UPDATE</command> triggers and all row-level
+    <literal>BEFORE</literal> <command>DELETE</command> triggers are fired on
+    the original partition.

Do we need to maintain triggers related behavior for logical
replication?  In logical replication, we use ExecSimpleRelationDelete
to perform Delete operation which is not aware of this special
behavior (execute before update trigger for this case).
