Not really. We *really* want to upgrade, but we're in the middle of
buying the new machine right now. There's also the issue of migrating
37GB of data which I don't look forward to, considering we'll need to
set up a slony replication for the entire thing to avoid the hours
of downtime necessary for a full dump/restore.

Not sure what you mean by that. It's just that this table has 27M
rows
extending over 4 years, and I'm not quite sure how to hint to that.
An index scan for a few days would be a tiny fraction of the entire
table, so PG being insistent on the sequence scans was confusing the
hell
out of me.
