Yeah, it sure is the same plan, and 8.2 seems to be a tad faster right
up to the hash join on user_id. Is user_id a textual datatype? I'm
wondering if the 8.2 installation is using a different locale --- the
speed of simple string comparisons can be horrifically worse in some
locales compared to others.
user_id is an int; they are both C locale.
