When parsing expressions like (old).colname and (old).* in a RETURNING list, the parser would lose track of the intended varreturningtype, and therefore return incorrect results. The root cause was code using GetNSItemByRangeTablePosn() to find a namespace item from its rtindex and levelsup, without taking into account returningtype, which would return the wrong namespace item. Fix by adding a new function GetNSItemByVar() that does take returningtype into account. Backpatch to v18, where support for RETURNING OLD/NEW was added.
