Function For Newly INSERTED VALUE

Hi All,

The following function is possible where input is 'Sequence Name' and output
is 'Inserted value' language 'plpgsql'

DECLARE
sequence ALIAS FOR $1;
inserted_rec integer;
sql text;
BEGIN
sql := 'SELECT INTO inserted_rec * from ' || sequence;
EXECUTE sql;
IF inserted_rec.last_value IS NULL THEN
RETURN 0;
ELSE
RETURN inserted_rec.last_value;
END IF;
END;

The same is working for the following

DECLARE
sequence ALIAS FOR $1;
inserted_rec integer;
sql text;
BEGIN
SELECT INTO inserted_rec * from sequencename;
IF inserted_rec.last_value IS NULL THEN
RETURN 0;
ELSE
RETURN inserted_rec.last_value;
END IF;
END;

How can I make use the top one.

With Best Regards,
