Quite possibly it is, see:
http://www.postfix.org/DATABASE_README.html#safe_db
The best solution is to use CDB, rather than Berkeley DB for these,
if your Postfix package supports CDB, use it. CDB performs updates
atomically and uses less memory, ... If switching to CDB is not an
option, use the approach recommended in the README file.

No, the issue is that your Berkeley is too new. This would not have
been a problem with Berkeley's Berkeley DB 1.85 (used by some BSD systems).
