For some reason, defining a new CRS is not working. The following error is reported: The proj4 definition of 'name' is not valid.

I'm defining a new CRS, from Settings -> Custom CRS... with:

Name: China Geodetic Coordinate System 2000
Parameters: +proj=geocent +ellps=GRS80 +units=m +no_defs

These parameters were pasted from EPSG:4479 definition.

I can use the calculator at the bottom to test the coordinate transformation, and it seems to works.

But it does not save the new CRS. It reports the following error: The proj4 definition of 'China Geodetic Coordinate System 2000' is not valid.

I've tried to add this projection to PostGIS and it works.

INSERT into spatial_ref_sys (srid, auth_name, auth_srid, proj4text, srtext) values ( 4479, 'EPSG', 4479, '+proj=geocent +ellps=GRS80 +units=m +no_defs ', 'GEOCCS["China Geodetic Coordinate System 2000",DATUM["China_2000",SPHEROID["CGCS2000",6378137,298.257222101,AUTHORITY["EPSG","1024"]],AUTHORITY["EPSG","1043"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["metre",1,AUTHORITY["EPSG","9001"]],AXIS["Geocentric X",OTHER],AXIS["Geocentric Y",OTHER],AXIS["Geocentric Z",NORTH],AUTHORITY["EPSG","4479"]]');

select ST_AsText(ST_Transform(ST_SetSRID(ST_Makepoint(114,30), 4326), 4479));
