Because files in gdal-data (>= 2.5.0~) cannot be used by libgdal20 (<< 2.5.0~). GDAL 2.5.0~beta1 introduced PROJ 6 support, which changed the content of proj-data significantly, making it incompatible with prior versions. This issue affected Ubuntu bionic where the newer GDAL is available via the UbuntuGIS PPA. > And if it was due to > upstream changes does that mean that postgis-enabled clusters are > essentially unmigratable unless you dump them in full before starting > the upgrade? Because if so, this should be mentioned in the Bullseye > release notes. PostGIS databases have never been able to be migrated during a distribution upgrade. You've always needed to recreate the databases in the new cluster. With the PostGIS library no longer including the minor version in its filename since 3.0, it might be possible to migrate PostGIS databases with pg_upgradecluster from bullseye to bookworm if PostGIS 3.x will be in bookworm too.
