Thanks for the patch! Looks good to me except the followings:

pg_basebackup.c:233: warning: passing argument 6 of
'ReceiveXlogStream' from incompatible pointer type

I got the above warning on compile. To fix this, the third argument
"segment_finished"
needs to be added to reached_end_position().

It seems confusing that *stream_continue()* returns TRUE when
streaming *cannot continue*, i.e.,
its name seems to be inconsistent with what it does. What about
renaming it to stream_stop?
Similarly, it also seems confusing that *continue_streaming()* returns
TRUE when streaming
*cannot continue*.
