New feature `--lazy-db`: `--reuse-db` with `--create-db` on DB error / ProgrammingError

What do you think about a new option --lazy-db, which would behave like --reuse-db, but falls back to --create-db when there's a DB error during the first test.

Would that be possible / feasible?
Could this be done by default, without a new option?

For example:

    def execute(self, sql, params=None):
        self.db.validate_no_broken_transaction()
        self.db.set_dirty()
        with self.db.wrap_database_errors:
            if params is None:
                return self.cursor.execute(sql)
            else:
>               return self.cursor.execute(sql, params)
E               ProgrammingError: relation "languages_plus_language" does not exist
E               LINE 1: ...."family", "languages_plus_language"."notes" FROM "languages...
E                                                                            ^

The issue does not name files or tests. Start by locating the existing --reuse-db and --create-db handling in pytest-django's database setup, then clarify whether the fallback should be opt-in or default. Done would require an agreed behavior and tests covering recovery from the first database error.
