Re: [database-devel] ByteString and Text - any conventions?

As an aside some people (Joey Adams IIRC, maybe others) have suggested that postgresql-simple should change the conversions so that ByteString represents postgresql's binary blobs, and not postgresql's text. (And get rid of the Binary type in the process) This seems a perfectly reasonable suggestion to me, though I'm not particularly inclined to change the API either. If you'd like to adopt this suggestion, be my guest. I don't think that API compatibility between the *-simples should be high priority; do whatever you think is best for sqlite-simple. Then hopefully in a few years we'll have some well-developed database-specific interfaces that can inform a next-generation HDBC interface.

I note that postgresql-simple and mysql-simple use ByteStrings exclusively in the API.

No, that's not how they work. The underlying representation in some places might be a ByteString, but the actual APIs don't use ByteStrings, they go through typeclasses.
