The estimated cost seems to be more than one disk page read per row
returned. This suggests to me that you have a huge amount of dead space
in that table --- try a VACUUM FULL on it. If that fixes the problem,
then you need to improve your housekeeping procedures on the 7.2
installation: run vacuums more often and ensure that your FSM settings
are large enough.
