Those API changes are not going to be back-patched to 9.4 as this is basically a new feature. For 9.4's pg_rewind, the problem does not concern this mailing list anyway, so let's discuss it directly on the project page on github. Just mentioning, but I am afraid that we are going to need a set of TRY/CATCH blocks with a wrapper function in plpgsql that does the failure legwork done here, or to export those functions in an extension with some copy/paste as all the necessary routines of genfile.c are not exposed externally, and to be sure that those functions are installed on the source server. I am not sure that I will be able to look at that in the short term unfortunately... Hence patches are welcome there and I will happily review, argue or integrate them if needed. The non-streaming option is not impacted in any case, so it's not like pg_rewind cannot be used at all on 9.4 or 9.3 instances.
