Viewing a table with \d in psql also shows the publications at table is in. If a publication is concurrently dropped, this shows an error, because the view pg_publication_tables internally uses pg_get_publication_tables(), which uses a catalog snapshot. This can be particularly annoying if a for-all-tables publication is concurrently dropped. To avoid that, write the query in psql differently. Expose the function pg_relation_is_publishable() to SQL and write the query using that. That still has a risk of being affected by concurrent catalog changes, but in this case it would be a table drop that causes problems, and then the psql \d command wouldn't be interesting anymore anyway.
