If that can't reasonably be done for 9.1, well, my next sentence was:
>> If not, I agree this can be 9.2 material.
It'd be sweet if it could still happen 9.1, but hardly a shock if it
can't. I didn't want to presume to make the call.
Like I said at the start, the alternative is to decide how noisy we
want to be about providing snapshot isolation on hot standbys when
SERIALIZABLE is requested, and figuring out where to document it.
