There is gradual movement towards having all the generation functions being completely compact. Personally I view the pretty flag as being a legacy setting formatting should be handled by a separate routine, which would be more expensive but much more flexible. merlin -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

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. > Is there a plan to add this feature on future version ? 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. -- Michael -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
