2500 bytes out of 82,500? Three percent. How valuable is that 3%? How does it balance with other wasted space in the table? Total space? > Is there no way to enforce a column type around the silent changes? You do understand the trade-offs involved in allowing variable length records in a database? that the database software has to either allocate the maximum width for each variable length field, or use an additional level of indirection in the indexing? Just a thought.
