And that takes us one step closer to PGXN's META.json file. Here's the spec:
 http://pgxn.org/meta/spec.txt

It includes a "prereqs" section, which looks like this:
      "prereqs": {         "runtime": {            "requires": {               "citext": 0,               "plpgsql": 0,
             "PostgreSQL": "8.0.0"            },            "recommends": {               "PostgreSQL": "8.4.0"
  }         }      },
