15049,postavoid add_metadata to insert duplicated entries,leogermani,,"when calling add_metadata, check if there is already an entry with the same object id, meta_key, and meta_value. If there is, return false so we dont have duplicated entries.

The unique paramater of the add_metadata does not handle with that, since it only cares about the meta_key not beeing duplicated.

When playing with multiple metadatas with the same meta_key, very often you have to check if a value already exists before adding it. I beleive add_metadata should handle it automatically.",enhancement,closed,normal,,Database,3.1,normal,duplicate,"metadata, post_meta, user_meta",
