Fix filtering of unsupported relations in logical replication
In the pgoutput plugin, skip changes for relations that are not
publishable, per is_publishable_class(). This concerns in particular
materialized views and information_schema tables. While those relations
cannot be part of a publication, per existing checks, they will be
considered by a FOR ALL TABLES publication. A subscription would not
actually apply changes for those relations, again per existing checks,
but trying to match incoming changes to local tables on the subscriber
would lead to errors if no matching local table exists. Skipping those
changes on the publisher avoids sending useless changes and eliminates
the error.
