Since nobody with real experience doing that has answered, I'll supply
my fewer than 2 Eurocents...
According to its manpage, it should be safe to use
pvresize --setphysicalvolumesize <newsize> <pvdevice>
prior to resizing the partition. It should complain if there are extents
in use beyond <newsize>.
I say "it should" because I never tried it. So make a backup, blahblah,
etcetera...

That is up to somebody with more knowledge to answer.
