Thread: [GENERAL] Text value within composite function result not quoted
Define a couple of types:
CREATE TYPE request_in AS
(
path text[],
args jsonb,
server text,
port smallint,
headers jsonb,
body bytea,
type_requested text[]
);
CREATE TYPE request_out AS
(
status smallint,
headers jsonb,
body text
);
and a function:
CREATE OR REPLACE FUNCTION request(
req request_in)
RETURNS "request_out"
LANGUAGE 'plv8'
COST 100.0
VOLATILE
AS $function$
return {'status': 200, 'headers': {}, 'body': "<body>Works!</body>"}
$function$;
call the function:
SELECT request(
(
'{}',
'{}'::jsonb,
'',
8080,
'{}'::jsonb,
''::bytea,
'{}')::request_in
)
get this result:
(200,{},<body>Works!</body>)
This is the textual representation of the result I get in psql and Ruby. Note that the textual final value is not quoted.
I imagine I can work out a way to deal with this, but this is not the most felicitous way of representing a text value that I can imagine.
Note that if I add a single space after “Works!”, I get quotes around the string.
This is 9.6.2 on MacOS.

As per spec:

Thanks. This is… inconvenient. I see nothing about an option to force quoting of strings. Is there no such option? If not, I suggest that it would be a useful addition.
