Description:        Create Function operator Broken?
Details: 

I have been through the online DOC's the FAQ and can find nothing wrong with
it.  So I am thinking its a bug.  

CREATE FUNCTION default_status() returns null AS 
'BEGIN
update status set wc to false, np to false, elk to false, sp1 to false, 
sp2 to false, wc_rep to false, np_rep to false, elk_rep to false, sp1_rep to
false, 
sp2_rep to false;
END;'
language 'sql';

It throughs a syntax error at the 'AS' and I can't seem to figure out why.

Sorry if this is not a real bug.
