That is an ancient backwards-compatibility hack that you should not rely on, and most certainly shouldn't try to make use of from user code. It exists because very ancient versions of pg_dump didn't know how to dump views as views. We're more likely to rip it out as no-longer-needed than to expand what it does. regards, tom lane
