EXCUSE ME, GUYS !

i forgot to add one monome:
7*(((to_char(date_trunc('month',now()),'D'))::INT2-1)/4)
which is stands for skip a first week of month in case it is not consist Wed

finally the select will be similar the following

SELECT 7*(((to_char(date_trunc('month',now()),'D'))::INT2-1)/4) + 1 -
(to_char(date_trunc('month',now()),'D'))::INT2  +  7*3-3 ;

4 - is a number of Wed in a week (in postgresql numeration)
