Unfortunately you have been careful to suppress any information that
might actually let someone give you useful advice ;-). There are
several threads in the archives about undesirable index-vs-sequential-
scan choices in 7.0; check pgsql-sql as well as pgsql-general for the
last month or so.
Also, 7.0.1, propagating now to an archive near you, contains some
fudge-factor twiddling to make it more willing to choose an indexscan.
We shall soon find out whether that made things better or worse for
typical uses...
