select date_trunc('month', current_date + '1 month'::interval) - '1 day'::interval + (((3 - 7 -
to_char(date_trunc('month',current_date + '1 month'::interval) - '1 day'::interval,'D')::int) %7)||'
days')::interval;
The "3" is the day of week (1 = Sunday, 7 = Saturday). This equation
will return the date of the last "x" of the current month. Change
"current_date" to be whatever date you wish to find the last "x" of.
