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.
