Thanks for your help. I try "extern C" for the inclusions and everything is OK. But now I have execution error (server crash), but it's another problem that I will try to solve.

The fact that the linker knows the argument data type indicates that you're trying to compile your code as C++. Postgres is written in C, not C++.
You can try putting extern "C" { ... } around your inclusions of Postgres header files, but you're likely to run into other problems later on. On the whole I'd recommend using plain C for backend functions if you possibly can.
