We certainly should allow it to be set as specified in the spec.  The
only question is whether it makes sense to provide a non-null default
if it is not set in that way.  I thought Magnus was arguing for that. 
I have no objection, and see potential use-cases where that would be
convenient.
To illustrate what I'm talking about, adding something like this to
the command line which starts Java would provide the non-null default: -DPGAPPNAME="Receipting - Traffic"
(or whatever name we choose for this in place of PGAPPNAME.)
This seems similar to what is proposed for libpq.
The effort to support that would not be significant -- something
along the order of   if (appName == NULL)       appName = System.getProperty("PGAPPNAME");
Do you object?
