For consistency, I guess it should say "lock object" instead of simply
"object" the description of all the columns up to (and including)
"objsubid", not only those of "virtualxid" and "transactionid".

I'd also slightly prefer "locked object" over "lock object", because
the lock itself probably isn't a standalone entity in the mind of
most users. And for people familiar with our locking infrastructure,
the actually correct term would be "lock tag" I believe.

In any case, +1 for improving the description there.
