pg_stat_reset only resets the data for the current database (the one
you issue it in).  Apparently most of your bloat is for some other
database(s).

If you've got a whole lot of databases, a possibly less painful
alternative to zapping them one at a time is to stop the server,
manually remove the stats file, start the server.
