I have a question based on 0001's commit message: "This patch adds a
new option to logical replication output plugin, to declare that it
does not use shared catalogs (i.e. catalogs that can be changed by
transactions running in other databases in the cluster).". In which
cases, currently plugin needs to access multi-database transactions or
transactions that need to access shared catalogs and on what basis a
plugin can decide that the changes it requires won't need any such
access.
