Bruce Momjian 1c1a4726eb docs: Improve window function docs
Specifically, the behavior of general-purpose and statistical aggregates
as window functions was not clearly documented, and terms were
inconsistently used.  Also add docs about the difference between
cume_dist and percent_rank, rather than just the formulas.
