Thanks Alvaro.  For now the patch uses the following error message:
+SELECT pg_replication_slot_advance('regression_slot3', '0/1'); -- error
+ERROR:  cannot move slot with non-reserved restart_lsn

Mentioning directly the column name of pg_replication_slots is confusing
I think.  Here are some suggestions of perhaps better error messages:
1) cannot move unreserved slot.
2) cannot move slot which has never been reserved.

Any better ideas?
