<p>Considering this statement, I opened a PR to remove the GHT

I've never used GHT myself. What I know though is this
major bug when<br>
GHT is used: <a
href="https://github.com/pgpointcloud/pointcloud/issues/196"
moz-do-not-send="true">https://github.com/pgpointcloud/pointcloud/issues/196</a>.
I<br>
haven't had the time to look into this bug.<br>
