change t.date2< dates.date to t.date2+0<dates.date, this will prevent
the query from trying to use the index on date2 because the where clause
now references an expression and not the column itself:
explain analyze
select sum(amount), dates.date as date
from transaction t
join (select get_dates as date from get_dates('09/17/08','09/24/08'))
dates
on (t.state='I' or t.date1 >= dates.date) and t.date2+0<dates.date
group by dates.date
Yup...that did the trick.....whodathunkit?
