Because it is hard to do. A lot of internals in Firebird and its clients rely on this maximum size (hint: the number itself fits in a 2-byte unsigned integer). It is not like you just need to update a MAX_ROW_SIZE constant and it is changed. Consider that PostgreSQL has a limit of around 8KB (with its default page size). However, PostgreSQL has the advantage that variable length fields can be automatically stored out-of-line (ie basically as a blob, but that is transparent to the user). > And in FB4 it is also 64 kB? Yes. Mark -- Mark Rotteveel
