The line number offsets are expected when applying to v10, but it looks
like you failed to transfer the attachment cleanly ... there were
certainly not CRs in it when I mailed it. The output on v10
should just look like
patching file src/backend/optimizer/plan/analyzejoins.c
patching file src/backend/utils/adt/selfuncs.c
Hunk #1 succeeded at 3270 (offset -91 lines).
Hunk #2 succeeded at 3304 (offset -91 lines).
Hunk #3 succeeded at 3313 (offset -91 lines).
Hunk #4 succeeded at 3393 (offset -91 lines).
Hunk #5 succeeded at 3570 (offset -91 lines).
