I'm looking for a database (relational would be preferred, but NoSQL is also okay) which can be run without an admin user. I want to setup the database with an admin user, but then delete the admin user forever and run the database only with non-admin users. Is there anything like that for Postgres, MongoDB, MySQL, etc.?
EDIT: The goal is to make the database 100% safe from unrestricted deletions. The normal users should only be able to insert data, deletions and edits should never be possible, also not for the admin.
Thanks for the help!
INSERT
s - no updates or deletes (via code). But, if your client has control of the back end, then you are in trouble! – Vérace Jun 2 '19 at 13:32
