On Publication rename, we need to only invalidate the RelationSyncCache entries corresponding to relations that are part of the publication being renamed. As part of this patch, we introduce a new invalidation message to invalidate the cache maintained by the logical decoding output plugin. We can't use existing relcache invalidation for this purpose, as that would unnecessarily cause relcache invalidations in other backends. This will improve performance by building fewer relation cache entries during logical replication.
