+Subject: Replace last PushOverrideSearchPath() call with
+ set_config_option().
+
+The two methods don't cooperate, so set_config_option("search_path",
+...) has been ineffective under non-empty overrideStack.  This defect
+enabled an attacker having database-level CREATE privilege to execute
+arbitrary code as the bootstrap superuser.  While that particular attack
+requires v13+ for the trusted extension attribute, other attacks are
+feasible in all supported versions.
+
+Standardize on the combination of NewGUCNestLevel() and
+set_config_option("search_path", ...).  It is newer than
+PushOverrideSearchPath(), more-prevalent, and has no known
+disadvantages.  The "override" mechanism remains for now, for
+compatibility with out-of-tree code.  Users should update such code,
+which likely suffers from the same sort of vulnerability closed here.
+Back-patch to v11 (all supported versions).
+
+Alexander Lakhin.  Reported by Alexander Lakhin.

+Subject: Handle RLS dependencies in inlined set-returning
+ functions properly.
+
+If an SRF in the FROM clause references a table having row-level
+security policies, and we inline that SRF into the calling query,
+we neglected to mark the plan as potentially dependent on which
+role is executing it.  This could lead to later executions in the
+same session returning or hiding rows that should have been hidden
+or returned instead.
+
+Our thanks to Wolfgang Walther for reporting this problem.
