Andrey Borodin complained through Telegram that he can't apply my patches using "git apply". After investigation of this problem, it appears that the reason is that I still use git context diff setup according to our wiki instruction (https://wiki.postgresql.org/wiki/Working_with_Git). I've look around some threads and realized that I'm probably the only guy who still sends context diff patches.
Attached patchset in universal diff format.
