In sar -B ouptut, I would naively expect pgpgin/s to equal majflt/s multiplied by the system page size. From man sar:

          pgpgin/s
                 Total number of kilobytes the system paged in  from  disk
                 per second.  Note: With old kernels (2.2.x) this value is
                 a number of blocks per second (and not kilobytes).

          majflt/s
                 Number  of  major  faults the system has made per second,
                 those which have required loading a memory page from disk
                 (post 2.5 kernels only).

But when I run it on my database server there appears to be no relationship between the two values:

$ sar -B

Clearly I'm wrong - could someone correct my misunderstanding?
