Try pvs/vgs/lvs instead (and use -o to get the details you want):

# pvs --segments
  PV         VG     Fmt  Attr PSize  PFree  Start SSize
  /dev/dm-0  laptop lvm2 a-   55.69G 32.00M     0   250
  /dev/dm-0  laptop lvm2 a-   55.69G 32.00M   250  1499
  /dev/dm-0  laptop lvm2 a-   55.69G 32.00M  1749    32
  /dev/dm-0  laptop lvm2 a-   55.69G 32.00M  1781     1
