postgresql/src/include/optimizer/planmain.h
Tom Lane cde9f852e0 Now that switch_outer processing no longer relies on being run after
join_references(), it's practical to consolidate all join_references()
processing into the set_plan_references traversal in setrefs.c.  This
seems considerably cleaner than the old way where we did it for join
quals in createplan.c and for targetlists in setrefs.c.
