That said, I don't think it's a good practice to use the control file

necessary to add an optional new format in a minor version at some point

Yes, PG_VERSION, as you wrote upthread already, is already fine for
the job, and FWIW, I have yet to see a case where being able to easily
detect the minor version in a data folder matters.
Regardless of PG_VERSION doing the job or not, shouldn't there be a bump
in PG_CONTROL_VERSION whenever there is a structural or semantic change
in the control file data? And wouldn't the easiest way to ensure that be
to bump the version with every release?
Also, can someone give me a good reason NOT to bump the version?
Thanks, Jan
