The SQL committee changed that recently --- SQL92 and SQL99 define the
view as
Identify the referential constraints defined in this catalog that
are owned by a given user.
I don't think we've gotten around to trying to sync information_schema
with SQL2003. (The whole concept that information_schema might be a
moving target is pretty disturbing :-()
