Comment (by Algunenano):

 > The visualisation library is mapbox.

 Mapbox, as a company, you appear to be using Mapbox GL JS
 (https://github.com/mapbox/mapbox-gl-js/).


 If I run your query I get this:
 {{{
 \x1a250a0333303312191803221509aa3cce1822a2049e0dcb0f5c74d30ba60499030f2880207802
 }}}

 Just the polygon:
 {{{
 POLYGON((3861 1575,4134 2422,3136 2468,3194 1722,3469 1517,3861 1575))
 }}}

 I've used that output to pass it to node-mapnik and decoded it as:
 {{{
 [
   {
     "name": "303",
     "extent": 4096,
     "version": 2,
     "features": [
       {
         "type": 3,
         "properties": {},
         "geometry": [
           9,
           7722,
           3150,
           34,
           546,
           1694,
           1995,
           92,
           116,
           1491,
           550,
           409,
           15
         ]
       }
     ]
   }
 ]
 }}}

 node-mapnik also confirms that the MVT is valid.

 I've tried downloading https://s3-eu-
 west-1.amazonaws.com/www.iventis.co.uk/assets/15/16597/11273.pbf and
 checking the tile with node-mapnik and, unless I'm missing something, that
 tile respects the MVT spec.


 I suggest you to open an issue to Mapbox GL detailing your problem and
 providing a copy of the MVT file generated by Postgis (11273.pbf); even
 better if you provide both the one generated by Postgis and the one
 generated using Mapnik.
