Log message:
    Promote row expressions to full-fledged citizens of the expression syntax,
    rather than allowing them only in a few special cases as before.  In
    particular you can now pass a ROW() construct to a function that accepts
    a rowtype parameter.  Internal generation of RowExprs fixes a number of
    corner cases that used to not work very well, such as referencing the
    whole-row result of a JOIN or subquery.  This represents a further step in
    the work I started a month or so back to make rowtype values into
    first-class citizens.
