Apparently, some SYSTEM LIBRARY Berkeley DB routine writes
uninitialized memory to file. Postfix does not write Berkeley DB
Have you sent a bug report to the FreeSBD bugs database?
Solaris had a similar problem years ago with the tar(1) command.
Not nice if you were putting tar files on anonymous FTP servers.
