When I walk the CRS list returned by proj_get_crs_info_list_from_database() I get a projection system with authority:code IAU_2015:19902 (and 39902, 49902, 59902, 60802 and probably more)

The PROJ_CRS_INFO.type I get here is 'PJ_TYPE_CRS', but when I create the CRS the type returned is 'PJ_TYPE_GEODETIC_CRS', so somehow proj_get_crs_info_list_from_database() is unable to find out what type of crs is.

Before 8.2.0 the type always matched.

All cases that have this issue have currently return PJ_TYPE_CRS and should have PJ_TYPE_GEODETIC_CRS.
