[postgis-users] Update "spatial_ref_sys" with "+towgs84" parameters

[feurbano at clix.pt]

Hi,
i need to update the epsg 23033 in spatial_ref_sys table adding the "+towgs84" parameters: (towgs84=-104.1,-49.1,-9.9,0.971,-2.917,0.714,-11.68).

do i have just to overwrite the original:
"+proj=utm +zone=33 +ellps=intl +units=m +no_defs "
with
"+proj=utm +zone=33 +ellps=intl +units=m +no_defs +towgs84=-104.1,-49.1,-9.9,0.971,-2.917,0.714,-11.68 "
?

Thanks,
Ferdinando
