Custom DATE format for ODBC (PostgreSQL)

Hi, 

I'm using TDP 4.2.0.207 to connect to a PostgreSQL database. The thing is I want the DATE and the DATETIME columns to be formatted in a different way:

Date = yyyy-MM-dd
TimeStamp = yyyy-MM-dd hh:mm:ss

I've tried to set up a custom format just for the dates by configuring: 

 Odbc:DATE=yyyy-MM-dd, (as mentioned in a very old thread here)

but this doesn't seem to work. I'm pretty sure that technique works in "Toad for SQL Server", where it is possible to have different formatting, but I'm not sure if TDP allows this for ODBC.

Does anybody know if this is feasible at all?
