SELECT
1-(to_char(date_trunc('month', now()::timestamp),'D'))::INT2 + 7*3-3
replace now with any date and you'll the the day number of a third Wed in that
month.
7 is a constant (factor 3 is a desired week number)
-3 is number of days to step back from sunday to a desired day of week
(-3 stands for Wed)
