Thanks, Brent. Your suggestions complete the approach I was considering.
There is no need for real-time response, to checking after each shift or day
-- or other time period -- will be sufficient.
I wonder if a workweek/holiday calendar table for PostgreSQL already
exists. If not I need to track down the procedure for creating one as Joe
Celko references such a calendar in his books. I think that any schema that
has temporal components needs such a table.
