1.14.4 (stable):

* Developer menu: Added Export Backup and Restore Backup menu items.
  These use PostgreSQL's pg_dump and pg_restore utilities, wrapping the
  dump and .glom file up in a .tar.gz.
  As well as allowing backups of data, this should make it easier to upgrade
  the PostgreSQL version, which some distros do automatically when upgrading
  to new major versions of Glom. This is possible because pg_restore can
  work with the pg_dump output of an older PostgreSQL version.
