Well, I could imagine certain cases, where applications only want to
list Postgresql servers newer than release x.y - since they depend on
certain new features of that release.
But you could be right, that the approach I've implemented only allows
filtering for "revision == x.y", but not the intended "revision >= x.y".
So maybe the release number, or a feature list (similar the capability
list of SMTP) should be put into the announcement's TXT record.
Well, but I do not consider that sub-type feature that important.
Ciao,
Mathias
