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

[Leon Smith]

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.

Best,
Leon
