unsafe int8 json

[exe-dealer]

select to_json(int8(9007199254740991 + 1))

JSON.parse parses all numbers as 53bit integers . When number is too big then JSON.parse silently loose precision what is not safe. Need to fix JSON.parse behavior (which will degrade perfomance) or document this pitfall

A minimal solution... perhaps folks could opt to have these values read as strings or bigint? I don't think the default behavior being to lose precision makes sense.
