Well, in pure SQL I don't think you could do it without resorting to
ugly tricks like defining an all_days table that had one row per day in
your range, then doing something like, "select from all_days a join xxx
x where a.day >= x.start_date and a.day <= x.end_date"
So . . . don't do that. What you want isn't really a pure relational
operation, so SQL isn't the right language for it. Either do it in your
application code, or write a server-side function.
In either case, this is more of a pgsql-general question, since it's not
specific to JDBC at all.
