Thanks for all the suggestions.

I have since realised what I'm missing: the PV/VG is actually created
from a partition, i.e the under-lying disk is /dev/xvda, so I have /boot
as /dev/xvda1 and the PV is /dev/xvda2. So, to resize it, I need to boot
into a rescue disk or live CD and rezize the /dev/xvda2 partition. The
PV should then reflect the increased size. I can then increase the
partition size and grow the FS.

Thanks,

R.
