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.
