I think that Amit originally suggested to have a view that provides
information about the objects in each publication (like table, tables
in schema, sequence ...).
So it currently is at the granularity level of the objects that are
actually added to the publication (TABLE t, ALL TABLES IN SCHEMA s)
I agree that the view is currently missing ALL TABLES publication
information, but I think it could be easily added.
Also, currently for the "objtype" column, the type "schema" does not
seem specific enough; maybe that should be instead named
"all-tables-in-schema" or similar.
