Want to configure UPnP on EdgeRouter-4?

Don't do it!

Introduction

As a former sysadmin that once helped ride herd over around 1,000 servers, of which around 10% were Internet-facing, I've never been a fan of autoconfiguation when it comes to punching holes through the firewall. I've seen the tripwire logs, and it's sobering.

The Problem

So enabling UPnP on my EdgeRouter-4 wasn't something I had on the roadmap, but when I ran into difficulty getting DLNA to work on the default VLAN, I thought it was worth looking into (never mind that, as I later learned, having UPnP turned on wasn't going make a bit of difference on my local network: another reason that mastering theory should always come before practice).

The script below isn't the fastest way to copy-and-paste from a protected 
Google Doc. Before trying it, I'd suggest following MikoFrosty's advice from 
the comments:

-- create point table using single-precision coordinates
CREATE TABLE pts (
  point_id serial,
  x        real,
  y        real
);
 
-- create a view that converts these into a PostGIS geometry
CREATE VIEW pts_view AS
SELECT point_id, ST_SetSRID(ST_MakePoint(x, y), 4326) AS geom FROM pts;
