PostGIS does not know EPSG 9234.

You can check this with:

select * from spatial_ref_sys where srid = 9234;

But EPSG.io provides handy code snippets to add it https://epsg.io/9234

Just run:

INSERT into spatial_ref_sys (srid, auth_name, auth_srid, proj4text, srtext) values ( 9234, 'EPSG', 9234, '+proj=pipeline +step +proj=axisswap +order=2,1 +step +proj=unitconvert +xy_in=deg +xy_out=rad +step +inv +proj=longlat +a=6377301.243 +rf=300.8017255 +step +proj=push +v_3 +step +proj=cart +a=6377301.243 +rf=300.8017255 +step +proj=helmert +x=230.25 +y=632.76 +z=161.03 +rx=-1.114 +ry=1.115 +rz=1.212 +s=12.584 +convention=coordinate_frame +step +inv +proj=cart +ellps=WGS84 +step +proj=pop +v_3 +step +proj=unitconvert +xy_in=rad +xy_out=deg +step +proj=axisswap +order=2,1', 'None');
