Problem writing function

["Christian Rengstl" <Christian.Rengstl@xxxxxxxxxxxxxxxxxxxxxxxx>]

Hi list,

the following function is created properly: 
CREATE OR REPLACE FUNCTION insert_into_table_overview(text, chr integer)
RETURNS void AS '
DECLARE
        in_table                ALIAS FOR $1;
        p RECORD;
BEGIN
	RAISE NOTICE ''in_table = %'', in_table;
	FOR p IN EXECUTE ''select distinct pid from '' ||
quote_ident(in_table) LOOP
		EXECUTE ''insert into table_overview(table_name, chr,
start_no, end_no, pid)
		select '' || quote_ident(tname) || '', chr,
min(entry_no), max(entry_no), p from '' || quote_ident(in_table);
	END LOOP;
END;
' LANGUAGE plpgsql;

But when i execute it with select
insert_into_table_overview('test1'::text, 1); i only get the following
output:
NOTICE:  in_table = test1

ERROR:  relation "test1" does not exist
CONTEXT:  SQL statement "select distinct pid from "test1""
PL/pgSQL function "insert_into_table_overview" line 6 at for over
execute statement

I am sure that there is something wrong with the quotes, but i just
can't find out what.
