Look in the pg_index catalog to see which indexes are marked as
clustered. In recent PG versions something like this is the easiest
way:

select indrelid::regclass, indexrelid::regclass from pg_index
where indisclustered;

I would expect the server to have finished out the command it was
currently working on before noticing the loss of connection, so
the odds are good that the cluster did finish.
