I'm only seeing trivial examples below, where you form the JSON objects
by plastering literals together. Does this work on a scenario where the
values come from a table?

The question is not at all theoretical -- right now our
archives.postgresql.org site uses a JSON file that's just a dump of a
table in a database. This file contains a list of lists, and a number
of properties for each (name, group it belongs to, description).
Obviously each one needs its label too.

Right now we generate this with a JSON Perl module.
