That part isn't new -- we added it sometime prior to 9.2:
8<--------------if (fail) level = ERROR;else level = NOTICE;
8<--------------
It allows dblink to throw a NOTICE on remote errors rather than an
actual ERROR, e.g. for an autonomous transaction.
From the docs (9.2 in this case)
8<--------------
fail_on_error
If true (the default when omitted) then an error thrown on the
remote side of the connection causes an error to also be thrown locally.
If false, the remote error is locally reported as a NOTICE, and the
function returns no rows.

Ok, will do.
