Tom Lane 2a64931c4b Salvage a little bit of work from a failed patch: simplify and speed up 
set_rel_width().  The code had been catering for the possibility of different
varnos in the relation targetlist, but this is impossible for a base relation
(and if it were possible, putting all the widths in the same RelOptInfo would
be wrong anyway).
