Description
Hello All.
I am trying to export data from PostGIS table using tilelive-copy:
`./tilelive-copy bridge:///tmp/poly.xml countries.mbtiles --maxzoom=7 --bounds=-180,-90,180,90`
[poly.xml.zip](https://github.com/mapbox/tilelive/files/1499794/poly.xml.zip)
After this is done, I've imported data to qGIS using plugin "Vector Tiles Reader" and observed some kind of grid squares:
How can I remove them? Polygons are splitted inside of this squares, checked this after data was exported to GeoJSON:
[countries.geojson.zip](https://github.com/mapbox/tilelive/files/1499801/countries.geojson.zip)
Please, help.

Research direction
Reproduce the command shown with the supplied poly.xml.zip and inspect the resulting countries.mbtiles in QGIS using the Vector Tiles Reader plugin. Compare the tile output with countries.geojson.zip to locate whether the grid squares arise during export or display; done means identifying a reproducible cause and a documented way to remove or avoid the artifacts.
