Short answer: yes.  Slightly longer answer: If you need to ask this
quetion then you should really talk to someone about network
programming but this is the wrong list.

If you are asking if PostgreSQL already does UDP then the answer is
no.  You need to write a server program that talks UDP in one direction
and TCP to PostgreSQL in the other direction.  Watch out for security
issues.
