Subject: [PATCH] Rename a nonterminal used in SQL/JSON grammar
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This renames json_output_clause_opt to json_returning_clause_opt,
because the new name makes more sense given that the governing
keyword is RETURNING.

Per suggestion from Álvaro Herrera.
