The patch works fine, but I think we must add some prefix to printed query.
Like that:

fabrizio=# \set ECHO error
fabrizio=# insert into foo values ('XXX');
ERROR: value too long for type character varying(2)
DETAIL: insert into foo values ('XXX');

or

fabrizio=# \set ECHO error
fabrizio=# insert into foo values ('XXX');
ERROR: value too long for type character varying(2)
QUERY: insert into foo values ('XXX');

This may help to filter the output with some tool like 'grep'.
