[gdal-dev] Getting all known coordinate systems.

I am updating to GDAL 3.0 (C# bindings). 

I need a list of all the supported coordinate systems in my application.

In the older versions, I requested all the known coordinate systems by
reading the csv files in the GDAL_DATA folder (pcs.csv, gcs.csv,...).

In the the new version, the csv files have been replaced by the proj.db
file. Does anyone know of a good way to get all the coordinate systems.
Should I just try to read the proj.db file myself and extract all the
records? Or is there some kind of method exposed for this?
