THAT WAS IT!!

Thank you very much.
Is there a way to change the type of "CURRENT_TIMESTAMP" to "timestamp without time zone" so that casting isn't needed?


BTW, isn't this a bug?

Anyone know what to do?   
I'd wonder if the type conversion is causing you problems.
CURRENT_TIMESTAMP - INTERVAL '10 minutes' is a timestamp with time zone
while the column is timestamp without time zone.  Casting
CURRENT_TIMESTAMP to timestamp without time zone seemed to make it able to
choose an index scan on 7.4.
