Jeff is right, PostgreSQL has released a new major yearly the last almost 25 years.

That would only be possible if they started with version -10!

Before version 10, the versioning scheme was different, and the first number was increased about once every five years: for example, 9.6 and 9.5 were consecutive yearly major releases. Version 7.0 was released around year 2000.
