pg_aclcheck: invalid user id #

Hi,

I found a strange behavior in PostgreSQL.
I created a table as user  pippo then I created a view based upon this
tables,
latter someone drops user pippo and now when I do:
select from view PostgreSQL show me this:
    pg_aclcheck: invalid user id #

I suppose it is because the user pippo the owner of this view, is any
more in the database
but if I do select from table it works fine.

Is this a bug?

Jose
