I must say that I share your concern here. I have no idea what's going
to happen with my ON CONFLICT patch, 9.5-wise. I hope that at least
the IGNORE variant makes it into 9.5, but I'm not sure that it will.
The ON CONFLICT IGNORE/UPDATE patch has existed in essentially the
same form since August, although research level work went into that
project as long ago as 2012. I'm not blaming anyone, but it's quite
discouraging that it has taken so much to get it to where it is now,
even though it's something that there is a huge, tangible demand for
(few other things are in the same category, and few of those have
actually been implemented). An enormous amount of effort went into
internals documentation (the Wiki pages), and into stress-testing
(Jeff Janes' "double entry bookkeeping" stress test, among others). I
hate to say it, but at some point I'll need to cut my loses.
To any interested contributor: If there is something that I can do to
help to advance the state of the ON CONFLICT UPDATE patch, let me
know. Perhaps there can be some useful reciprocal arrangement with
review time. That's not ideal, but I see no alternative.
