I wouldn't say the metadata is "complex". Looks quite familiar to that
of pg_settings (besides that, it was just a brainstorming, not a formal
proposal).
The optional fields are basically NULLABLE attributes in pg_settings.
That is, they only make sense depending on other values (in this case,
the parameter name). All of the attributes that are required for tools
to work are marked as non optional.
So optional fields are either purely optional (i.e., only for tools
that want to use them; everyone else may ignore, but preserve, them) and
some other are just NULLABLEs, depending on the parameter).
In any case, my idea is just to open up the question and search for the
best possible set of data to be represented, and then, the best possible
syntax / file format for it.
