It is a bit unclear from the report whether the submitter needsss to
be able to recover from failures.  If the application only uses the
database for temporary data, it may be OK to start with a fresh

The submitter says "he never use rollback" and think that he does not

database to become inconsistent should something unforeseen happen
that make it impossible to commit a transaction (e.g., full disk).
