Log Message:
-----------
Give a suitable HINT when an INSERT's data source is a RowExpr containing
the same number of columns expected by the insert. This suggests that there
were extra parentheses that converted the intended column list into a row
expression.
Original patch by Marko Tiikkaja, rather heavily editorialized by me.
