>From the wiki article, *Switching to the new wview_extended schema <https://github.com/weewx/weewx/wiki/Switching-to-the-new-wview_extended-schema>* :
WeeWX V4.x offers a new schema wview_extended, with many new types. You may find many of these types useful and want to switch to it. Before explaining how to do this, it's worth noting: 1. In WeeWX, the schemas found in schemas/wview.py and schemas/wview_extended.py are used *only when the database is created*. Thereafter, the schema is read from the database itself, and the Python versions are not used again. 2. While wview_extended is the new, default, schema for V4.x, it is not necessary to "upgrade" to it. Your old wview schema will continue to work just fine. Switch to the new schema only if you find the new types useful. 3. If you just need to add one or two new types, you may find it easier to use the tool weectl database add-column <https://www.weewx.com/docs/latest/utilities/weectl-database/#add-a-new-observation-type-to-the-database> .
