Hi,

Sorry if this mail comes twice, I had some troubles with sending it.

I refer to this issue https://github.com/MapServer/MapServer/issues/6843. I 
found a workaround for making the workflow "KKJ projections into ETRS-GK-FIN" 
to work correctly and it is to add an old style "epsg" file into the Proj data 
directory. However, the mail 
https://lists.osgeo.org/pipermail/mapserver-dev/2023-January/016907.html  tells 
that
"And if you have an "epsg" text file, it will have precedence over proj.db for 
+init=epsg:XXXX codes (although I don't recommend this, because proj.db will be 
completely ignored for any epsg entry, so you'd better make sure your text file 
is complete enough)"

Does it mean that the epsg file should contain entries for all the coordinate 
systems that our Mapserver supports for input and output, and that the proj.db 
database would then be completely skipped, with all the benefits that it has?
