As far as I can see, that shouldn't make any difference. Both queries still do the bitmap heap scan, and have almost exactly the same cost.

You may have a point there Matthew, they both appear to do a scan on the email table (Why?). But for whatever reason, I swear the second method is significantly faster! If I run the new style query first, then the original style (to_tsquery as q) then the original style still takes longer, even with the new style cached!

Incidentally, how can I clear the cache in between queries?
