That nobody in the right mind would use in production for YEARS. That
said there is a very real problem here. For a very, very long time the
recommended way (wrong way in fact) to do partitioning was based on
rules. Now, those in the know immediately said, "WTF" but I bet you that
a lot of people that we don't know about are using rules for partitioning.
We definitely need a warning period that this is going away. That said,
I don't know that we need a whole release cycle. If we start announcing
now (or before the new year) that in 9.3 we will not have rules, that
gives people 9-10 months to deal with the issue and that is assuming
that we are dealing with early adopters, which we aren't because early
adopters are not going to be using rules.
