While I find this proposal very useful, I think the interface can be improved.

Consider SELECT pg_update_version(commit_hash) so we can do stuff like
SELECT pg_update_version('REL_18_2') or SELECT pg_update_version('HEAD~10000').
In future we can even create a bisect facility, so when user encounters a bug in their production they can iterate over several commits to trace root cause.


Best regards, Andrey Borodin.
