No, I don't think so. The use-case for this sort of thing seems to me
to be messages that are directed to the user or DBA, and don't want to
be decorated with a lot of information about where they came from.
That determination is usually pretty clear when you write the code.
Moreover, if we don't attach the specification to particular RAISE
commands, it's going to be "all or nothing", which is most definitely
not the right thing.
Having said that, if we allow "USING context = boolean_expression",
it'd be possible for the plpgsql coder to make the behavior run-time
adjustable if he wanted.
