No analyze for 7.1.3.
Just ran vacuum a few minutes before the query. No boost at all. Even
with SET enable_seqscan = 0 it still does a table scan.
Dann, I can attest to 7.2 having a much better planner and performance
than 7.1 did. Can you upgrade?

VACUUM or VACUUM ANALYZE? Standalone ANALYZE was not in 7.1 but
VACUUM ANALYZE does what you need to do...

Those big round numbers suggest that you haven't run vacuum analyze on
all of your tables.

If not, the stats weren't
