51.52. 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.
