to_timestamp with its present behavior is, IMO, a poorly designed function
that would never be accepted today.  Concrete proposals for either fixing
or deprecating (or both) are welcome.  Fixing it should not
cause unnecessary errors to be raised.

My main point is that I'm inclined to deprecate it.

My second point is if you are going to use this badly designed function you
need to protect yourself.

My understanding is that is not going to change for 9.6.
