We will probably find cases where we need codes not defined by SQL
(since we have non-SQL features).  If there is room to invent our
own codes then I have no objection to this.

Unless that BSD implementation is ready to go, I think we'd be talking
about relying on GPL'd (not LGPL'd) code for an essential component of
the system functionality.  Given RMS' recent antics I am much less
comfortable with that than I might once have been.
