Notice the word "static" in the definition of inv_getsize() in
src/backend/storage/large_object/inv_api.c:

static uint32
inv_getsize(LargeObjectDesc *obj_desc)
{
...
}

I don't know if there's a good reason for inv_getsize() being static.
Maybe your code could use inv_seek() instead.

If you compile with warning flags, then you should at least have
gotten a warning like "implicit declaration of function `inv_getsize'".
That's a hint that something's wrong.
