Looks good.

Agree this should go into v18.

According to Microsoft documentation, LONG_PTR is __int64, and so using
PRId64 would seem to be appropriate. However, I wonder whether it
wouldn't be simpler to print the original paramHandle either as %p or
cast to uintptr_t, to avoid having two separate code paths.

These are dealing with actual long long int values, to using %lld/%llu
seems appropriate.

These are using off_t or pg_off_t, for which there is no format
placeholder, so you have to cast it to something.
