The PostgreSQL Project will be releasing a security update for all supported versions on Thursday April 4th, 2013. This release will include a fix for a high-exposure security vulnerability. All users are strongly urged to apply the update as soon as it is available.
We are providing this advance notice so that users may schedule an update of their production systems on or shortly after April 4th.
As always, update releases only require installation of packages and a database system restart. You do not need to dump/restore or use pg_upgrade for this update release.
