It seems like something like that could work.  I'd be inclined to change
the ereport() macro itself, not errmsg/errdetail/etc.  The domain name
could be passed in at ereport and then used when evaluating the
messages.

A possible problem is that some places use _() (ie, gettext) directly
instead of leaving it to the elog.c code to apply translation.  But I
suppose we might be able to redefine _() too.
