Some of this stuff's in our old porting guide, which should still be in file storage ...
Oracle 9i at least implements the SQL standard timestamp types. Eventually we should be able to merge much of this stuff but that's just a light-at-the-end-of-the-tunnel comment. Obviously we don't even support 9i at the moment so we're not in any position to force people to use it :)
Oracle 8.1.7 supports one form of CASE, not both of the SQL standard forms.
