I think I've heard of scripts grepping the output of pg_controldata for

While I'm not opposed to improving the labels, I would vote against your
second, abbreviated scheme because it would make things ambiguous for
simple grep-based scripts.
I had exactly this kind of discussion just a few days ago with a customer,
who wants to use the output in their scripts and was a little worried about
the compatibility between major versions.
I don't think we do guarantuee any output format compatibility between
corresponding symbols in major versions explicitly, but given that
pg_controldata seems to have a broad use case here, we should maybe
document it somewhere wether to discourage or encourage people to rely on
it?
