My memory is lousy at the best of times, but when have we had a minor
release that would have broken this due to changed format? OTOH, the
Primary and Backup servers need the same config settings (e.g.
--enable-integer-datetimes), architecture, compiler, etc, do they not?
Probably working from an identical set of binaries would be ideal.
