- If you look the Postgis Git repository :<br>
- <a href="https://git.osgeo.org/gitea/postgis/postgis/src/commit/2b5868ca90c2eac99cb53d5242ace55f01499b23/topology/README" rel="noreferrer" target="_blank">https://git.osgeo.org/gitea/postgis/postgis/src/commit/2b5868ca90c2eac99cb53d5242ace55f01499b23/topology/README</a><br>
- <a href="https://git.osgeo.org/gitea/postgis/postgis/commits/branch/master/topology?page=19" rel="noreferrer" target="_blank">https://git.osgeo.org/gitea/postgis/postgis/commits/branch/master/topology?page=19</a><br>
<br>
A lot of work is / was done by Sandro Santilli (<a href="https://git.osgeo.org/gitea/strk" rel="noreferrer" target="_blank">https://git.osgeo.org/gitea/strk</a>)<br>
He works currently for NIBIO - Norwegian Institute of Bioeconomy Research and they develop web services to edit features with PostGIS Topology :<br>
<a href="https://gitlab.com/nibioopensource" rel="noreferrer" target="_blank">https://gitlab.com/nibioopensource</a><br>
<br>
> which are the users that are using the topology for working with tables with millions of rows (I am asking this because I have read, but I do not remember where, that PostGIS topology is very slow and appropriate only for small datasets).<br>
<br>
- So for users, Norway at least to manage their National Land Resource Map.<br>
- And here are the slides of a presentation at FOSS4G in 2015 "What happens when you put 1 billion points into Postgis Topology?"<br>
