Leo and I attended PostgresVision 2018 which ended a couple of days ago.
We gave a talk on spatial extensions with main focus being PostGIS. Here are links to our slides PostgresVision2018_SpatialExtensions HTML version
PDF.
Unfortunately there are no slides of the pgRouting part, except the one that says PGRouting Live Demos because Leo will only do live demos. He has no fear of his demos not working.
Side note, if you are on windows and use the PostGIS bundle, all the extensions listed in the PostGIS box of the spatial extensions diagram, as well as the pointcloud, pgRouting, and ogr_fdw are included in the bundle.
