Yes, I went ahead and tried the original suggestion.
Here is what the added function went in as:
CREATE OR REPLACE FUNCTION xml_is_ok(x text)
RETURNS boolean AS
$BODY$
BEGIN
PERFORM XMLPARSE( DOCUMENT x::XML );
RETURN TRUE;
EXCEPTION WHEN OTHERS THEN
RETURN FALSE;
END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE
COST 100;
ALTER FUNCTION xml_is_ok(text) OWNER TO postgres;
It worked fine. Thanks Mike and David.
The only other issue is that when I benchmarked it on a 5,000 record data
set that I have,
the original XML2 function ('xml_is_well_formed') took about 9.5 seconds
and this (deprecation driven) replacement took about 17.2 seconds.
