Well, not *everything* can be represented as UTF-8; I think this is particularly an issue with Asian languages. If we chose to do it, I think that per-column encoding support would end up looking a lot like per-column collation support: it would be yet another per-column property along with typoid, typmod, and typcollation. I'm not entirely sure it's worth it, although FWIW I do believe Oracle has something like this. At any rate, it seems like quite a lot of work. Another idea would be to do something like what we do for range types - i.e. allow a user to declare a type that is a differently-encoded version of some base type. But even that seems pretty hard. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
