[GRASS-dev] PROJ version in WinGRASS

[Roger Bivand]

In: https://lists.osgeo.org/pipermail/grass-stats/2021-April/001834.html
I draw attention to an issue raised with regard to the version of PROJ 
proj.db bundled with WinGRASS. Across the EPSG 9/10 border, table and 
field names change, so PROJ itself builds differently, and g.proj is built 
to handle the proj.db/EPSG version it "sees". If PROJ_LIB is changed to a 
different proj.db/EPSG version, obviously problems occur.

Is there a way to declare the EPSG version in g.proj, preferably before 
7.8.6 ships? For now the work-around in rgrass7 is to trap the error found 
when g.proj expects EPSG 9 and is pointed at 10, and fall back from WKT2 
to Proj4 string representation.
