* The ST_MakeValid(geom) example could have been expanded to include ST_IsValidDetail()

* It is arguably wrong to say that Lat/Lng (EPSG:4326) data is one of the projections. I meant to present that there are spatial reference systems and you use one per table, so calling Lat/Lng one of them made one less turn in the directions for use. But so it goes.
