The problem with the hstore scripts is that you had to copy the 1.0
script, change a couple of lines, and call that 1.1, and you also had to
provide the 1.0--1.1 script file.

The solution would be to be able to create hstore 1.1 from 1.0
automatically and I sent over a very simple patch to do that, albeit
after the deadline for the current CF (that's why it's not listed).

Maybe that's simple enough to be considered? (re-attaching here)

I think not that many people are using 9.1 in production already. Also
bear in mind that the mechanism is not made only for contrib, it makes
sense to ship in-house procedure code as an extension too.
