+ Remove public execute privilege
+ from contrib/adminpack's
+ pg_logfile_rotate() function (Stephen Frost)
+
+
+ pg_logfile_rotate() is a deprecated wrapper
+ for the core function pg_rotate_logfile().
+ When that function was changed to rely on SQL privileges for access
+ control rather than a hard-coded superuser
+ check, pg_logfile_rotate() should have been
+ updated as well, but the need for this was missed. Hence,
+ if adminpack is installed, any user could
+ request a logfile rotation, creating a minor security issue.
+
+
+ After installing this update, administrators should
+ update adminpack by performing
+ ALTER EXTENSION adminpack UPDATE in each
+ database in which adminpack is installed.
