Comment:

 End of the day, we take the answers from Proj and consider them golden. If
 you can show a case that is different from ST_Transform than from using
 cs2cs, that's something I am (vaguely) interested in. Vaguely, because it
 is still very dependent on your local environment, what grids you have
 installed and so on, which is outside our control, but hopefully in
 general you would see ST_Transform matching cs2cs run on the same machine.
