Correct :-(

Do you have a backup on tape or somewhere?

A lot of parts are redundantly stored on every physical volume.
*But* you need the PV structure *and* the PE mapping table (that's the one
which translates between LV and PV addresses) which is in
/etc/lvmconf/VGName.conf or deaper in the history (default depth 10) kept there.

It wouldn't help because the above unique information isn't on any of
the other physical volumes.

Likely all but the crahed one PV.

In case you have a recent backup of /etc/lvmconf/*, you can make use of
that to vgcfgrestore your PV and run vgscan.
