[Mobilitydb-users] Query regarding upcasting and downcasting tgeompoint datatype

[Esteban Zimanyi]

Dear Sharath

We could implement such a function, it would not be very complicated.
However, could you please elaborate a little more about your requirements
because already some of the MobilityDB functions take into account the Z
dimension only if *both* arguments are in 3D.
