I am concerned about setting debug_query_string to NULL, calling
ereport(), and then resetting it might cause problems because of cases
where ereport might want to access debug_query_string for other uses,
for cases where ereport doesn't return to the reset code (but I assume
that is handled), and for cases like pgmonitor that would stop a
backend, read debug_query_string, and disconnect.

I can create a global variable to control this, but the new elog level
seemed cleaner.
