I was logged in as a superuser (postgres).  Most of the schema were owned by
postgres but some containing stored functions were not, and most of the
tables in the public schema were owned by another user.  Based on your
comments, I dumped the database with the No Owner option and restored it to
a test database logged in as postgres.  All the objects in the test database
are owned by postgres and now the views in information_schema are showing
the expected information.

Thanks for your (prompt) help, Tom.
