    Doc: in back branches, don't call it a row constructor if it isn't really.
    
    Before commit 906bfcad7, we were not actually processing the righthand
    side of a multiple-column assignment in UPDATE as a row constructor:
    it was just a parenthesized list of expressions.  Call it that rather
    than risking confusion by people who would expect the documented behaviors
    of row constructors to apply.
    
    Back-patch to 9.5; before that, the text correctly described the construct
    as a "list of independent expressions".

    According to the standard, the source value for a parenthesized sub-list of
    column names can be any row-valued expression yielding the correct number
