AFAICS, those tables are already in the subscriber database. And will it generate error or warning? (I'm not sure how this functionality deals with schemas.) Also, why do I want to replicate a information schema table? Their contents are static and, by default, it is already in each database.
Information schema isn't a catalog but I think it is good to exclude it from FOR ALL TABLES clause because the use case is almost zero. Of course, it should be documented. Also, if someone wants to replicate an information schema table, it could do it with ALTER PUBLICATION. -- Euler Taveira Timbira - http://www.timbira.com.br/ PostgreSQL: Consultoria, Desenvolvimento, Suporte 24x7 e Treinamento -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
