#
The catalog pg_subscription
contains all existing logical replication subscriptions. For more information about logical replication see Chapter 30.
Unlike most system catalogs, pg_subscription
is shared across all databases of a cluster: there is only one copy of pg_subscription
per cluster, not one per database.
Access to the column subconninfo
is revoked from normal users, because it could contain plain-text passwords.
