Is there a safe way to install fresh PROJ, for example v8.2, in a Debian Linux server, for use with (for example) PostGIS v3?
The installation of PROJ was implicit in the PostGIS's, I never do directly... And it seems that PostGIS must be prepared for a major PROJ's version upgrade (7.x to 8.x).
RATIONALE: I'm looking for modern DGGS projections, so I need modern PROJ. Even using POSTGIS v3.2, the PROJ version is 7, but
s2 projection for example needs PROJ v8.2+. Other questions, like this, shows a bug that perhaps is an "old-PROJ problem".
