Do you mean that the programmer can't control PGD even when it's not
connected, or that your circuit is loading PGD to the point that the
programmer can no longer drive it?

As a test, you can run TEST_PICPRG with the target disconnected from the
programmer.  The commands DATH and DATL should make PGD go high and low
respectively.  If they do when open but not when connected to your circuit,
then your circuit is loading the line too much.
