Not any direct way that I know of :( If you have a lot of spaces in a
JSON blob between each object, it may be worth casting it once to
jsonb. This takes an extra round of conversion overhead though.

I don't recall plans in this area. Maybe there's room for a
jsonb_compact(). core has already jsonb_pretty(), and that would be
what has the less overhead when doing the binary/text conversion.
