I think the opening paragraphs contrasting json/jsonb be needs
refinement. json is going to be slightly faster than jsonb for input
*and* output. For example, in one application I store fairly large
json objects containing pre-compiled static polygon data that is
simply flipped up to google maps. This case will likely be pessimal
for jsonb. For the next paragaph, I'd like to expand it a bit on
'specialized needs' and boil it down to specific uses cases.
Basically, json will likely be more compact in most cases and slightly
faster for input/output; jsonb would be preferred in any context
where processing, or searching or extensive server side parsing is
employed.
If you agree, I'd be happy to do that...
