Would we be the first major database to support custom collation rules? This sounds useful for testing, experimentation, hacking, etc. What are some of the use cases? Is it helpful to comply with unusual or outdated standards or formats? Maybe there are people using special delimiters/terminators and they need them to be treated a certain way during comparisons?
