[postgis-users] PostgreSQL 13, PostGIS 3.1 import - could not form projection

[karsten]

Yes will try to get this to work and report back here. 

The stack exchange issue mentioned that it worked with an older gdal version

so will try with both different proj and gdal combinations

There's something very particular about your environment and I don't know
what it is. Try upgrading your proj version, and jimmying with other version
combinations. There's nothing special about the SRID numbers, they work fine
for me locally. I can't invest the time in setting up a mirror system that
matches yours. If there's something specific about proj 6.3.1 maybe? (both
you and the stack exchange issue)
