[postgis-users] pointcloud : change pcid ?

[Rémi Cura]

I'm sorry I think I was unclear.
I don't want to acces point,
I just want to change the pcid of a patch.
For the moment it seems to imply a complete destruction/reconstruction of a
new,
which is really really not efficient.

Basically in this case I would like a function PC_SetPCID(pcpatch)
I understand that such function is very hard to create in the genral case,
because you would have to put mappings between attributes.


Cheers.
Rémi-C
