The use of JSON will not be ideal -- not in this sense. For example, at $work, we’re using it in place of an EAV model.
Hencemost rows have the same keys (or a subset of known keys). Or think of your favorite JSON API: every call to
http://api.pgxn.org/user/$username.jsonis going to have a very similar structure.
