pg_subscription
The catalog pg_subscription
contains all existing
logical replication subscriptions. For more information about logical
replication see Chapter 31.
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.
