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'.

sure, good idea.
