Tom Lane 866bad9543 Add a rank/(rank+1) normalization option to ts_rank(). While the usefulness
of this seems a bit marginal, if it's useful enough to be shown in the manual
then we probably ought to support doing it without double evaluation of the
ts_rank function.  Per my proposal earlier today.
