The columns are actually blank....it's the other rows I left out with
the row-level locks:
925282231 | 925280527 | | 62814 | RowExclusiveLock | t
925282208 | 925280527 | | 62814 | RowExclusiveLock | t

925282211 | 925280527 | | 62814 | RowExclusiveLock | t
925282213 | 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).
