That's not true. The first release (plpgsql -> plpgsql2) will be a
major release.
After that, we can do minor releases for the following X years, until
we possible need for a new major version.
Each minor release would be guaranteed not to break any backwards compatibility.
plpgsql -> plpgsql2 would be the single giant leap we take into the future.
I think this reasoning is quite compatible with the versioning policy
of the project in general, where we distinguish between major and
minor releases.
