  1. Tweak docs for log_statement_sample_rate

Dear Adrien,

That was my lack of understanding. Sorry.

By the way, I think the name of this parameter should be changed.
In the Cambridge dictionary, the word "rate" means as follows:

the speed at which something happens or changes, 
or the amount or number of times it happens or changes in a particular period.

This parameter represents "probability" whether it log, 
therefore this name is inappropriate.
You should use "probability" or "ratio", I think.


Next week I will give you some comments about your good source.
