But while PostgreSQL doesn't really have a choice here - it cannot be expected to subdivide itself - extensions (at least external ones - PostGIS is one I have in mind presently) - can and often do attempt to support multiple versions of PostgreSQL for whatever major versions of their product they are offering. For these it is possible to adhere to the "change one thing at a time principle" and to treat the extensions as not being part of "ALL the changes from one major version to the target version..."
You may make that exception for an external extension like PostGIS. But I don't think it is valid for one distributed in sync with the core system in the contrib package, like pg_stat_statements. Which happens to be the one named in the subject line of this entire discussion.
