I think that is too specific.  You can see a session waiting for a SHARE
lock on a transaction whenever it is waiting for a row lock, since row
locks are not permanently stored in the shared memory lock table.
Rather than adding a paragraph about the specific incident that happened
to you, you should describe the general mechanism.
