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.
