LGTM, and one minor comment we need to address eventually.

As interface header I'd expect that every function put to sqlInt.h would be
properly documented, and wanted to complain that `sql_bind_uuid()` is not
accompanied with doxygen block ... but then discovered that majority of 
`sql_bind_*` functions (with exception of `sql_bind_boolean()`) were not 
documented at all, and actually this terse introduction looks more consistent
than if it would be documented :(

So, it looks like it's ok for today, but eventually we should return here and
make sure it's reasonably documented/commented out.
