Title:
  postgresql-plperl-9.5 blocks do-release-upgrade from 16.04 to 18.04

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  The packet postgresql-plperl (and probably other addon packages for
  postgresql) blocks do-release-upgrade from 16.04LTS to 18.04LTS.

  This requiresthen requires a complete dump-and-restore cycle:

  1) Stop user applications
  2) do a full database export
  3) stop postgresql
  4) uninstall postgresql and all subpackages
  5) delete remaining tablespace directories
  6) do-release-upgrade
  7) reinstall postgresql and the required subpackages
  8) restore database from backup
  9) start user applications

  This requires a much longer downtime than just using
  pg_upgradecluster, because the database is offline during the whole
  do-release-upgrade cycle.
