I would be very surprised if Belchertown is adding data to the database as it is an extension that generates output only, as far as I can see it does not contain any code to add data to loop packets/archive records nor add/alter any archive records to/in the database.
wee_extension --list only shows those extensions that were installed using the wee_extension utility (and that have not been subsequently uninstalled using wee_extension); it does not show any other extensions, add-ons etc that were not installed by wee_extension nor does it tell us anything about what driver or services are being used. Far better to see a startup log with debug=1 <https://github.com/weewx/weewx/wiki/Help!-Posting-to-weewx-user#the-system-log> as well as a wee_debug <http://weewx.com/docs/utilities.htm#wee_debug_utility> report. This will show us exactly how WeeWX is configured and specifically what driver and services are in use.
