I have uploaded version 0.1.0 to the vault. It introduces prepared 
statements and placeholders. No doc on this yet but it's easy to use, e.g.

  BOOST_AUTO(st, db.prepare(insert_into(p)(p.id, p.first_name, p.name, 
p.age).values(_, _, _, _)));
  st.execute(3, "Bart", "Simpson", 9);
  st.execute(4, "Lisa", "Simpson", 7);
  st.execute(5, "Maggie", "Simpson", 0);

It also works with update, delete and select. Placeholders are allowed 
in predicates as well. Parameters are type-safe, if they don't agree 
with the type of their corresponding placeholder (as deduced by the 
context in which it is used), you will get a compilation error.
