SELECT current_date + interval '3 days' as Saturday

          saturday
          -------------
          2006-03-04 00:00:00

But in MS-SQL, it's

     SELECT dateadd(d, 3, getdate()) as Saturday
          Saturday
          --------------
          2006-03-04 14:16:19.060

Should SA even have a role in trying to "paper over" these kinds of differences?

Does it make sense to develop a set of function abstractions that would work across these databases?

I think that for base operations on standard types covered by the ansi standard such as dates it would be interesting to have abstractions that would map to concrete operations on non-ansi dbs. (like it already does with string concatenations)
