About functions

Hi,

While working on functions, I had a problem:

I wanted to write a function whict would drop my function. It is simply as
below:

CREATE FUNCTION dropfunc(text) RETURNS integer AS '
DROP FUNCTION $1 ;
SELECT 1;
'
LANGUAGE SQL;

But PostgreSQL answers:

test=# ERROR: parser: parse error at or near "$1"

What is the error in here?

Regards and best wishes,
