dblink_get_result returns NULL if remote query throws error

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/9.3/static/contrib-dblink-get-result.html
Description:

Please consider clarifying this page:
https://www.postgresql.org/docs/current/static/contrib-dblink-get-result.html
to state that if you call 
select dblink_get_result ('mylink',false), you will receive back a NULL if
the remote query threw an error. It is not clear on the page. At least an
example would be nice.

Thanks!
