Pragma's are not a very nice solution: they're compiler-specific, and 
other compilers might warn about them.  But Richard is right: you're 
supposed to include headers like <pqxx/connection> which in turn include 
headers like <pqxx/connection.hxx>, and the only protection against 
double inclusion is in that first file.
