People,

Thanks for your help with my problem with NULL values.  Also, particular
thanks for a hint on where to find a copy of SQL-92 standard, something
I didn't already have.  It was annoying to discover that UNIQUE didn't
have what I felt was the "obvious" meaning, but it doesn't and PostgreSQL
does operate correctly.

David
