+      An unprivileged user of <filename>dblink</filename>
+      or <filename>postgres_fdw</filename> could bypass the checks intended
+      to prevent use of server-side credentials, such as
+      a <filename>~/.pgpass</filename> file owned by the operating-system
+      user running the server.  Servers allowing peer authentication on
+      local connections are particularly vulnerable.  Other attacks such

+      are also possible.
+      Attacking <filename>postgres_fdw</filename> in this way requires the

+      parameters, but any user with access to <filename>dblink</filename>
+      could exploit the problem.
+      In general, an attacker with the ability to select the connection

+      could cause mischief, though other plausible attack scenarios are
+      harder to think of.
