It was pointed out to me, that earlier this year there was a useful
discussion about similar matters "PGC_SIGHUP shared_buffers?" [1]. From
what I see the patch series falls into the "re-map" category in that
thread.

Hi

I tried to apply patches, but failed. I suppose the problem with CRLF in the end of lines in the patch files. At least,
aftermanual change of v1-0001 and v1-0002 from CRLF to LF patches applied, but it was not helped for v1-0003 - v1.0005
-they have also other mistakes during patch process. Could you check patch files and place them in correct format? 

The new status of this patch is: Waiting on Author

Well, I'm going to rebase the patch if that's what you mean. But just
FYI -- it could be applied without any issues to the base commit
mentioned in the series.
