Comment 3 for bug 186831

 postgresql-common (84) unstable; urgency=low
 .
   * Add t/140_pg_config.t: Check correct output of pg_config, to avoid bugs
     like #455509 and #462037 in the future.
   * t/040_upgrade.t: Create and cd into an inaccessible test directory.
   * pg_upgradecluster: Chdir to / before the upgrade to avoid confusing error
     messages about inaccessible cwd.
   * debian/README.Debian: Update for 8.3 being the default version. Drop
     description of 7.4 autovacuum daemon magic, since it is obsolete now.
   * debian/postgresql-common.templates: Point to README.Debian.
   * debian/postgresql-common.cron.d: Update for 8.3, and add warnings and doc
     pointer about enabling regular VACUUM FULL. (LP: #186831)
   * PgCommon.pm, get_cluster_locales(): Print proper error message when server
     package is removed, but not purged, and a cluster still exists.
     (Closes: #463070)
   * t/030_errors.t, t/130_nonroot_admin.t: Check pg_dropcluster/
     pg_createcluster error message when being called with insufficient
     privileges.
   * pg_createcluster, pg_dropcluster: Point out that program needs to be run
     as root when creating/removing config or data directory fails.
     (Closes: #460576)
   * t/090_multicluster.t: Remove test case for nonexisting PGSERVICE value,
     since this is not reliably reported in psql.
   * t/140_pg_config.t: Skip pg_config test for 8.1. It's known broken in Etch
     (pg_config was only shipped in libpq-def) and irrelevant in Lenny.
