Agreed, I don't think we want to distribute that term any wider than
that file.

I was thinking of adding it to the file's header like
 * NOTES
 *        Some of the terms used in this file are of historic nature: "retrieve"
 *        was the PostQUEL keyword for what today is SELECT. "RIR" stands for
 *        "Retrieve-Instead-Retrieve", that is an ON SELECT INSTEAD rule (which
 *        has to be unconditional and where only one rule can exist on each
 *        relation).

since both retrieve and RIR are used in a bunch of places.
