* IDENTIFICATION * IDENTIFICATION
* src/backend/rewrite/rewriteHandler.c * src/backend/rewrite/rewriteHandler.c
* *
* 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 DO INSTEAD SELECT rule
* (which has to be unconditional and where only one rule can exist on each
* relation).
