New versioning scheme

Exactly.  I think it is time for us to realize that our beloved "major.minor"
versioning is a failure, both at a marketing and a technical level. It's a
lofty idea, but causes way more harm than good in real life. People on
pgsql-hackers know that 9.1 and 9.5 are wildly different beasts. Clients?
They are running "Postgres 9". So I'm all in favor of doing away with
major and minor.

However, this may break some things that expect a triple number, so one
solution is to market it as Postgres 10, Postgres 11, etc. but keep the
minor number - which shall never be changed. Thus, our next releases
become:

10.0.0
11.0.0
12.0.0

And the revisions stay the same:

10.0.1
10.0.2
10.0.3
11.0.1
12.0.1
12.0.2

etc.
