Hmmm. On second thought, maybe one or the other is enough, either restrict the parameter to values where the approximation is good, or put out a clear documentation about when the approximation is not very good, but it may be still useful even if not precise.

So I would be in favor of expanding the documentation but not restricting the parameter beyond avoiding value 1.0.

I have removed restriction and expanded documentation in attaching patch v5. 

Also I have recorded patch to CF 2017-09 —  https://commitfest.postgresql.org/14/1206/.
