Обсуждение: plpgsql test function

This simple test function fails.

----------------------------------------------
drop function testit(text);
create function testit(text) returns text as '
DECLARE
    myval text;
BEGIN
    myval:= $1;
    return myval;
END;
' language 'plpgsql';

select testit('testing');
select testit(''testing'');
----------------------------------------------

Result:

DROP
CREATE
ERROR:  parser: parse error at or near ""
ERROR:  parser: parse error at or near "testing"

It doesn't seem like the parameter passing mechanism is working.
What am i missing?

TIA,
-km

    All I can see is a missing whitespace after  "myval".
    The PL/pgSQL parser isn't that smart as the main one.
