Describe the bug

Creating a function via a CREATE FUNCTION command doesn't work.

To Reproduce

1. Open a new Query Tab
2. Paste the below code:

CREATE FUNCTION x() RETURNS INT LANGUAGE plpgsql AS $$
BEGIN 
  RETURN 1;
END;
$$;

3. Ctrl-A (Edit -> Select All)
4. F9 (Query -> Run)

Screenshots or Crash reports

I get this error message:

ERROR:  unterminated dollar-quoted string at or near "$$
BEGIN 
  RETURN 1"
LINE 1: CREATE FUNCTION x() RETURNS INT LANGUAGE 
plpgsql AS $$
                                                            ^

Executing the same command from psql works well so the syntax is correct. Heidi also should be able to execute it, I think.
