Dear Maintainer,

The autopkgtests for postgresql-plproxy have been failing ever since
2.6-2 because postgres is not network namespace aware.

In Ubuntu, the attached patch was applied to achieve the following:

  * d/t/installcheck fixes:
    - Passing a port to pg_virtualenv even with newnet does not avoid
      port collisions, as pg_virtualenv (via pg_createcluster) is only
      looking at the configured clusters on the filesystem, not what is
      running in the current network namespace. Set an alternative
      PG_CLUSTER_CONF_ROOT instead, and set it before we call
    - Set the socket directory for pg_createcluster, as we are using the
      standard port and that can lead to conflicts. This also requires
      making the AUTOPKGTEST_TMP directory world-writeable so the
      postgres user can write socket information there.

Thanks for considering the patch.
