First thank you for this new table mode! It will be very helpful, especially the primary key mode which cannot not null anymore. What about unique indices and null. I know that Sqlite like to follow Postgresql but I already run into some bugs because of it. Maybe there could be some STRICT unique indices too which would only allow one null value in an index. Very often I work around it by defining some special value like -1 but sometimes this is not easy and using null as unique "non value" would be very helpful. Thank you again for the STRICT tables. :-) Marco
