But, I don't see a corresponding change in the else part of the query: else { printfPQExpBuffer(&buf, "SELECT pubname\n" "FROM pg_catalog.pg_publication p\n" "JOIN pg_catalog.pg_publication_rel pr ON p.oid = pr.prpubid\n" "WHERE pr.prrelid = '%s'\n" "UNION ALL\n" "SELECT pubname\n" "FROM pg_catalog.pg_publication p\n" "WHERE p.puballtables AND pg_catalog.pg_relation_is_publishable('%s')\n" "ORDER BY 1;", oid, oid); } Don't we need to do that to keep it working with previous versions? -- With Regards, Amit Kapila.
