The columns are actually blank....it's the other rows I left out with
the row-level locks:
925282231 | 925280527 |             | 62814 | RowExclusiveLock    | t925282208 | 925280527 |             | 62814 |
RowExclusiveLock   | t          |           |  1192675195 | 62814 | ExclusiveLock       | t925282207 | 925280527 |
      | 62814 | RowExclusiveLock    | t925282025 | 925280527 |             | 62814 | AccessShareLock     | t925282025 |
925280527|             | 62814 | RowExclusiveLock    | t925282206 | 925280527 |             | 62814 | RowExclusiveLock

RowExclusiveLock   | t925282209 | 925280527 |             | 62814 | RowExclusiveLock    | t925281338 | 925280527 |
      | 62814 | AccessShareLock     | t925281338 | 925280527 |             | 62814 | RowExclusiveLock    | t925282211 |
925280527|             | 62814 | RowExclusiveLock    | t925282213 | 925280527 |             | 62814 | RowExclusiveLock
 | t
 

So I assume the processes waiting on the TX were waiting for one or more
of those rows.

Now I just need to figure out why the rows were locked for such a long
time (the row level locks are mostly on one table and various indexes of
that table).
