+      A malicious user of either the publisher or subscriber database
+      could potentially cause execution of arbitrary SQL code by the role
+      running replication, which is often a superuser.  Some of the risks
+      here are equivalent to those described in CVE-2018-1058, and are
+      mitigated in this patch by ensuring that the replication sender and
+      receiver execute with empty <varname>search_path</varname> settings.
+      (As with CVE-2018-1058, that change might cause problems for
+      under-qualified names used in replicated tables' DDL.)  Other risks
+      are inherent in replicating objects that belong to untrusted roles;
+      the most we can do is document that there is a hazard to consider.

+      Make contrib modules' installation scripts more secure (Tom Lane)
+     </para>
+
+     <para>
+      Attacks similar to those described in CVE-2018-1058 could be carried
+      out against an extension installation script, if the attacker can
+      create objects in either the extension's target schema or the schema
+      of some prerequisite extension.  Since extensions often require
+      superuser privilege to install, this can open a path to obtaining
+      superuser privilege.  To mitigate this risk, be more careful about
+      the <varname>search_path</varname> used to run an installation
+      script; disable <varname>check_function_bodies</varname> within the
+      script; and fix catalog-adjustment queries used in some contrib
+      modules to ensure they are secure.  Also provide documentation to
+      help third-party extension authors make their installation scripts
+      secure.  This is not a complete solution; extensions that depend on
+      other extensions can still be at risk if installed carelessly.
