As Peter mentioned in https://www.postgresql.org/message-id/ba76aeb0-2f84-d180-268f-ea0f5ace4...@2ndquadrant.com the decision has been taken to simplify our user-facing version numbering system to be a two-component number. Since there have been questions about the details of that, I wanted to emphasize that we are not breaking compatibility with code-facing version numbering. In particular, PG_VERSION_NUM and related representations will look like 1000xx, 1100xx, etc in future branches, as though the second component were zero in an old-style version number.
Somebody needs to come up with a patch implementing this changeover. I will work on it if no one else feels motivated to (but I'd be just as happy to let someone else do it). If we do not have such a patch ready to go when the 9.6 branch is made on Aug 15, I will probably transiently stamp HEAD as 9.7 rather than have a situation where "version 10" appears in a three-part version number. (External code will need some cue as to how to format displays from PG_VERSION_NUM, so we should have a hard and fast rule that major >= 10 means new style.) Also, it strikes me that we need a new convention for how we talk about release branches informally. Up to now, mentioning say "9.5" without any further qualification in a PG-list message was usually sufficient to indicate a branch number, but I do not think that will work so well if one just writes "10". I'm tempted to start writing branch numbers as something like "PG10" or "v10".
