I would argue that now is the perfect time for a number of reasons:

(1) 9.x regardless of the fact that it is just a number, reflects a
massive change as a whole.

(2) HS/SR are going to be scary things to use for at least 6 months to a
year. That is not to disparage the hard work, just that they are big
enough and invasive enough to make sure we get through a couple of dot
revs before we start seriously recommending them.

(3) As Bruce suggests, we are on year 6 now. I think we can take the

(4) The 8.3 issue wasn't nearly as bad as Tom is making it out to be.
Yes, there was a lot of WTF going on, but only by people that aren't

(5) The time to change it is NOW, so that when we go into beta it
becomes a serious in your face, we have to fix this if we want to be
compatible with v9 of PostgreSQL.
