I don't know. I haven't looked at the patches themselves in any
detail. I was merely replying to a specific question about
monotonicity with respect to a particular data type.

However, my impression from reading this thread is that the patches
haven't had a great deal of in-depth review yet, there are still a
number of design ideas that people might wish to explore in more
detail, it probably needs more careful analysis to verify correctness,
and more testing. That makes me think that it's not feasible to get
anything committable in less than a week, and it would be better to
defer this.

Thank you for your feedback, either way I am happy that at least
now it received some attention.

I am testing an iterative single variable/expression and to find the
simplest expression x that is the cause of all the variation in the
pathkey expression, saving this in the plan info, and thus, reduce
the per index work.

Alexandre
