> log "Reconnecting to the database..."
> RailsMultisite::ConnectionManagement::establish\_connection(db: @current\_db)

> This reconnect is not switching us back to correct database because of that check
> https://github.com/discourse/rails\_multisite/blob/master/lib/rails\_multisite/connection\_management.rb#L181
> Basically, it finds existing handler and it thinks that we are connected to correct DB and this step can be skipped.

> To solve it, we can reload RailsMultisite::ConnectionManagement which creates a new instance of that class
