Your function has already sucked all the rows out of the cursor before
it returns it, so it's not surprising that further reads from the cursor
produce nothing.
You could try rewinding the cursor (see MOVE) but I'm not sure that will
help in this case, since the function has carefully ensured that none of
the rows pass the cursor query's WHERE condition anymore. I think that
since the cursor used SELECT FOR UPDATE, it will not return the updated
rows even after rewinding. (I could be wrong though, so it's worth
trying.)
I think you need to rethink what you're doing. This seems like a fairly
silly application design: why not do all the processing you need on these
rows in one place? Or at the very least, don't use one cursor to serve
two masters. Possibly you could have the function return the rows itself
instead of passing back a refcursor.
