It turns out that pvresize won't "defrag" physical extents, therefore it is a matter of luck whether you can shrink a PV. Reading around the issue it seems you can manually move PEs using pvmove, lvdisplay, guesswork and luck. There might be scope for a "pvdefrag" command in libguestfs at some point ...
