right, I was looking for the alternate input methods that you allude to.  I 
have been unable to find an example of exactly how to do this.

I readily admit that I didn't read much into it, but I think you are 
mistaken.  If you look at the following links you will see that postgresql

escape characters.  I was simply saying that this behavior might be a way of 
preventing that from happening again.
