I am getting Dollar sign unterminated - postgresql

Question

I want to create a function like below which inserts data as per the input given. But I keep on getting an error about undetermined dollar sign.
CREATE OR REPLACE FUNCTION test_generate
(
ref REFCURSOR,
_id INTEGER
)
RETURNS refcursor AS $$

CREATE TEMP TABLE test_1
(

r.id,
rd.code
FROM

INNER JOIN
raw_table rd
ON
rd.test_2_id = r.id
LEFT JOIN
observe_test o
ON
o.raw_table_id = rd.id
WHERE o.id IS NULL
AND COALESCE(rd.processed, 0) = 0;
ELSE
INSERT INTO test_1
SELECT
rd.id,
r.id,
rd.code
FROM
test_2 r
INNER JOIN
raw_table rd
ON rd.test_2_id = r.id
WHERE r.id = _id;
END IF;
DROP TABLE IF EXISTS tmp_test_2_error;

$$ LANGUAGE plpgsql VOLATILE COST 100;
I am not able to run this procedure.
Can you please help me where I have done wrong?

I am using squirrel and face the same question as you.
until I found that:
-- Note that if you want to create the function under Squirrel SQL,
-- you must go to Sessions->Session Properties
-- then SQL tab and change the Statement Separator from ';' to something else
-- (for intance //). Otherwise Squirrel SQL sends one piece to the server
-- that stops at the first encountered ';', and the server cannot make
-- sense of it. With the separator changed as suggested, you type everything
-- as above and end with
-- ...
-- end;
-- $$ language plpgsql
-- //
--
-- You can then restore the default separator, or use the new one for
-- all queries ...
