I didn't try your query, but I guess it complains about RTRIM, because
it should accept text as an argument. If it is a case, you can try to dig in
direction of something like this:

> SELECT p.id_po, p.line_number, replace(replace(replace(RTRIM(XMLAGG(XMLELEMENT(name C, regexp_replace(p.protocol_number,'([[:cntrl:]])','', 'g'))ORDER BY 1)::text

(with explicit type casting)

best regards,
Ilya
