Detailed Description

template<std::floating_point T>
struct pqxx::internal::float_string_traits< T >

String traits for builtin floating-point types.

It would make sense to define this directly as the definition for pqxx::string_traits<T> where T is a std::floating_point. However Visual Studio 2022 does not seem to accept that syntax.

So instead, we create a separate base class for std::floating_point types and then derive specialisations of pqxx::string_traits from that.
