PG_SUBSCRIPTION

PG_SUBSCRIPTION contains all existing logical replication subscriptions. This system catalog is accessible only to system administrators.

Unlike most system catalogs, PG_SUBSCRIPTION is shared across all databases in a database instance. Each database instance has only one copy, not one copy per database.
