There's no longer much pressure to switch the default GIN opclass for jsonb, but there was still some unhappiness with the name "jsonb_hash_ops", since hashing is no longer a distinguishing property of that opclass, and anyway it seems like a relatively minor detail. At the suggestion of Heikki Linnakangas, we'll use "jsonb_path_ops" instead; that captures the important characteristic that each index entry depends on the entire path from the document root to the indexed value. Also add a user-facing explanation of the implementation properties of these two opclasses.
