Обсуждение: psql \dv+ shows view size as 0 bytes

\dv+ shows the size of views as "0 bytes".  This doesn't make any sense;
I think it should show null.  Maybe this is even the fault of the
backend functions for returning a number to display in the first place.

It doesn't sound useful whether it's 0 or NULL in that output.  Why
have the column in the first place when it can't have a value?  Is it
somehow required for inclusion in the output of \d+ ?
