Looking at the forked forecast sources I see the following in install.py
'DataBindings': {
'forecast_binding': {
'manager': 'weewx.manager.Manager',
'schema': 'user.forecast.schema',
'table_name': 'archive',
'database': 'forecast_sqlite'}},
So it'll use its own database with its own schema. No bugs I see at all.
I use the chaunceygardiner forked forecast extension and other than editing
weewx.conf and rolling my own index.html.tmpl to salt to taste, it works
fine for me for many years now.
