Detailed Description

template<typename TYPE>
struct pqxx::forbidden_conversion< TYPE >

String traits for a forbidden type conversion.

If you have a C++ type for which you explicitly wish to forbid SQL conversion, you can derive a pqxx::string_traits specialisation for that type from this struct. Any attempt to convert the type will then fail to build, and produce an error mentioning oops_forbidden_conversion.
