But that requires the addition of an extra, indexed Text column to the table.
And the "status" reference table is not the only place I need this construct;
I have other relationships to reference tables which are similar. It would
amount to adding probably a total of 25-40 columns to various tables in my
database overall; maybe 100MB of completely redundant data. :-(
I'll wait for ASSERTIONS, I think.
