Thanks for committing this nice feature!

Here is one minor comment.

+      <primary><varname>deduplicate_items</varname></primary>
+      <secondary>storage parameter</secondary>

This should be

     <primary><varname>deduplicate_items</varname> storage parameter</primary>

<secondary> for reloption is necessary only when the GUC parameter
with the same name of the reloption exists. So, for example, you can
see that <secondary> is used in vacuum_cleanup_index_scale_factor
but not in buffering reloption.
