The manual says:

RowDescription,zero or more DataRow messages, and then CommandComplete. COPY to or from the frontend invokes special
protocolas described in Section 46.2.5. All other query types normally produce only a CommandComplete message.

If a multiple return sets from a procedure are returned just like
multiple return sets from multiple queries, that's already covered by
the protocol.
