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
rulecan exist on each*      relation).
 

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