Hi,
I think commit 83e176ec1, which moved block sampling functions to
utils/misc/sampling.c, forgot to update this comment in
commands/analyze.c: "This algorithm is from Jeff Vitter's paper (see
full citation below)"; since the citation was also moved to
utils/misc/sampling.c, I think the "see full citation below" part
should be updated accordingly. Attached is a patch for that.
Best regards,
