The other side of that coin is that we might get useful comments from
testers on how the feature ought to work. I don't agree with the notion
that all feature details must be graven on stone tablets before we start
trying to get feedback from people outside the core development community.
The same point applies to the FDW C API questions, or to RLS, or to the
"expanded objects" work that I did. (I'd really love it if the PostGIS
folk would try to use that sometime before it's too late to adjust the
definition...) Now, you could argue that people likely to have useful
input on those issues are fully capable of working with git tip, and you'd
probably be right, but would they do so? As Simon says nearby, publishing
an alpha/beta/whatever is our signal to the wider community that it's time
for them to start paying attention. I do not think they will look at 9.5
until we do that; and I think it'll be our loss if they don't start
looking at these things soon.
