So no light there ... next step would be to set log_statement = all
and see what pg_dump's last few queries before failing are.
I see this with correct quoting:

2016-12-15 12:06:15.211 EST [693] LOG:  statement: SELECT c.oid
    FROM pg_catalog.pg_class c
         LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
    WHERE c.relkind in ('r', 'S', 'v', 'm', 'f', 'P')
      AND c.relname ~ '^(Statuses)$'
      AND pg_catalog.pg_table_is_visible(c.oid)

and this if I omit quotes:

2016-12-15 12:07:19.735 EST [741] LOG:  statement: SELECT c.oid
    FROM pg_catalog.pg_class c
         LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
    WHERE c.relkind in ('r', 'S', 'v', 'm', 'f', 'P')
      AND c.relname ~ '^(statuses)$'
      AND pg_catalog.pg_table_is_visible(c.oid)

(This test is on HEAD; I suppose the 'P' case is pretty new...)
