You are assuming I gave it any thought at all. :-) I converted it to a date type (create table ratings2 as ....) [EMAIL PROTECTED]:~/netflix/download$ time psql -c "select count(*) from ratings" netflix count ----------- 100480507 (1 row) real 1m29.852s user 0m0.002s sys 0m0.005s That's about the right increase based on the reduction in data size. OK, I guess I am crying wolf, 47M/sec isn't all that bad for the system. ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
