I haven’t delved into it, but you likely lose the ability to round-trip your json strings, just as in postgreSQL’s jsonb type. Jsonb_extract(jsonb(foo), '€')

I haven’t delved into it, but you likely lose the ability to round-trip your json strings, just as in postgreSQL’s jsonb type. Jsonb_extract(jsonb(foo), '€') likely - will remove/change white space in ‘foo’, - does not guarantee to keep field order - will fail if a dictionary in the ‘foo’ string has duplicate fields - will fail if ‘foo’ doesn’t contain a valid json string
