The catalog <code class="structname">pg_subscription</code> contains all existing
logical replication subscriptions. For more information about logical
replication see <a class="xref" href="logical-replication.html" title="Chapter 31. Logical Replication">Chapter 31</a>.
</p><p>
Unlike most system catalogs, <code class="structname">pg_subscription</code> is
shared across all databases of a cluster: there is only one copy
of <code class="structname">pg_subscription</code> per cluster, not one per
database.
</p><p>
Access to the column <code class="structfield">subconninfo</code> is revoked from
normal users, because it could contain plain-text passwords.
