## E.312. Release 7.3.19

Release date: 2007-04-23

This release contains fixes from 7.3.18, including a security fix.

### E.312.1. Migration to Version 7.3.19

A dump/restore is not required for those running 7.3.X. However, if you are upgrading from a version earlier than 7.3.13, see Section E.318.

### E.312.2. Changes

- Support explicit placement of the temporary-table schema within `search_path`, and disable searching it for functions and operators (Tom)

  This is needed to allow a security-definer function to set a truly secure value of `search_path`. Without it, an unprivileged SQL user can use temporary objects to execute code with the privileges of the security-definer function (CVE-2007-2138). See `CREATE FUNCTION` for more information.

- Fix potential-data-corruption bug in how `VACUUM FULL` handles `UPDATE` chains (Tom, Pavan Deolasee)
