A couple of places in the planner need to generate whole-row Vars, and were cutting corners by setting vartype = RECORDOID in the Vars, even in cases where there's an identifiable named composite type for the RTE being referenced. While we mostly got away with this, it failed when there was also a parser-generated whole-row reference to the same RTE, because the two Vars weren't equal() due to the difference in vartype. Fix by providing a subroutine the planner can call to generate whole-row Vars the same way the parser does. Per bug #5716 from Andrew Tipton. Back-patch to 9.0 where one of the bogus calls was introduced (the other one is new in HEAD).
