Is your feature request related to a problem? Please describe.

Hello, the contains (@>) and contained (<@) operators only supports for now Range types. In the docs they can be used also with Array types, Geometric types and Json

• Array

  ARRAY[1,4,3] @> ARRAY[3,1,3]
  ARRAY[2,2,7] <@ ARRAY[1,7,4,2,6]

• Geometric

  circle '<(0,0),2>' @> point '(1,1)'
  point '(1,1)' <@ circle '<(0,0),2>'

• Json

  '{"a":1, "b":2}'::jsonb @> '{"b":2}'::jsonb
  '{"b":2}'::jsonb <@ '{"a":1, "b":2}'::jsonb

I think when using List the Postgrest the request failed, doesn't recognize the operator as @acupofjose mentioned in #15

Describe the solution you'd like

If you can support those types specially arrays. Thank you very much.
