I have the following SQL function:

CREATE OR REPLACE FUNCTION public.my_function(texts text []) 
RETURNS SETOF table 
LANGUAGE sql STABLE
AS $ function $
SELECT  * FROM table 
$ function $

I have added this to my database and the function that Hasura exposes over the GraphQL API looks like:

query MyQuery($texts: _text = "") {
  my_function(args: {texts: $texts}) {
    id
  }
}

where $texts ends up needing to be an argument that looks like "{a,b,c}". In my opinion this is a bit awkward. Furthermore, the _text type is not documented by Hasura:

It would seem that an argument of type text[] would more naturally map to [String!]. Is there a reason not to do that? Also, is there a work around on my end that can force Hasura to choose this mapping?
