that seems to be the killer:
and time >= extract ('epoch' from timestamp '2009-08-12')
and time < extract ('epoch' from timestamp '2009-08-13' )
You probably need an index on time/epoch:
CREATE INDEX foo ON table(extract ('epoch' from timestamp time );
or something like that, vacuum analyze and retry.
