Uploaded Changelog:

  * Merge from debian unstable, remaining changes:
    - Build dep on libpq-dev as postgresql-dev doesn't exist
    - Update maintainer to match Debian Maintainer Field Spec.

My preference for changelog in this situation:

  * Merge from debian unstable, remaining changes:
    - Update maintainer to match Debian Maintainer Field Spec.
  * Build dep on libpq-dev as postgresql-dev doesn't exist

Reasoning:

    When new changes are made to a package, they should be highlighted, whereas the "remaining changes" were presumably already there.
