RPC function returning XML

[guizmo05]

Hi,
I have a function returning XML
Here the definition and the return directive.

CREATE or replace FUNCTION "myfunction"()
RETURNS xml 
....
BEGIN
...
return ttext::xml;
END

When i test it in postgresql, it's ok ->
when i test it in a browser (mydomainename.org/rpc/myfunction) postgrest seems to add quotes -> ""
the browser isn't able to interpret it.
if i force the response header by adding : perform set_config('response.headers', json_build_array(json_build_object('content-Type', 'text/xml')): -> i get an error -> error on line 1 at column 1: Start tag expected, '<' not found

Is there a way to have a xml stream returning by a postgresql function with postgrest without the quotes?

Thank you

Paul

I've found a solution
just add a domain in postgresql
create domain "*/*" as bytea;

and change the return type of the function with "/"
don't forget to keep:
perform set_config('response.headers', json_build_array(json_build_object('content-Type', 'text/xml'))

and voilà!
-> browser get the good output in xml!
