There is a lot of place for debating here. For example, std::copy might 
be considered to be just duplicating std::transform (with identity), but 
very few people would agree to drop it.

But I get your point.

SOCI provides a couple of seemingly unrelated ways of interfacing, but 
each of them has some rationale, from performance to distinction between 
static and dynamic bindings. In principle the library would go with just 
single-row-at-a-time dynamic bindings, but that would not allow us to 
exploit the ultimate performance that some servers can provide with 
direct binary data transport.

I'm very confident that the interface will be thoroughly scrutinized 
here. ;-)
