Close.

Postgres' original query language was PostQUEL, an extended version of
University Ingres' QUEL. You can still see some of the original verbiage
in the query rule rewriter ... things like fireRIRrules() and the like.
RIR is short for "retrieve instead retrieve", and RETRIEVE was the
command replaced today by SELECT. An RIR rule is what implements a view.
