I have search for information about the difference between "unique index" and "unique constraint" in PostgreSQL without getting to a specific answer, so I kindly ask for an explanation that helps me clarify such concept.
The way I think of it is, that since the SQL standard does not mention indices an INDEX (UNIQUE or otherwise) is just the databases application of a constraint. So for practical purposes they are the same thing.
