I'm not sure if I'm understanding you correctly, but if you're asking "can I stop users from creating new SQL functions that use my existing C function in strange ways" then the answer is no. All you can do is stop postgresql from seeing the function under any circumstances, by declaring it "static" or using some other way to strip the symbol from the resulting library.
