I had updated to the latest version before.
In the meantime, I deleted the “metabase” database, deleted the app, downloaded again, and reinstalled the app.
I am again on a startup screen, but I am not being asked to set up a new account, but only to provide login credentials.
No new database by the name of “metabase” appears to have been created (checking with “\l” on Postgres console).
What would be steps to completely purge any trace of Metabase from my system so that I can start from scratch. Just deleting the DB and reinstalling the app does not appear to have done that. (And frankly I am not even sure, if the database was in any way related to the app-based install or from an earlierattempt of setting up a server version.)
