this is not uncommon. this is what I've been dealing with earlier today in Postgres:

  json_build_object ( VARIADIC "any" ) → json

  jsonb_build_object ( VARIADIC "any" ) → jsonb

  Builds a JSON object out of a variadic argument list.
  By convention, the argument list consists of alternating keys and values.
  Key arguments are coerced to text; value arguments are converted as per to_json or to_jsonb.

      json_build_object('foo', 1, 2, row(3,'bar')) → {"foo" : 1, "2" : {"f1":3,"f2":"bar"}}

I'm really used to writing them on new lines.

  json_build_object(
    'foo', 1,
    2, row(3, 'bar')
  )
