namespace-name can't be specified in N1QL

As per below forum info :

https://forums.couchbase.com/t/couchbase-bucket-vbucket-namespace-keyspace-hash-key-definitions-plus-best-practice-for-key-definitions/22560/14

At present only default, system allowed in N1QL query and you can’t create any other name-space as per couchbase forum ...however in this link there is reference of 'main' namespace. Looks like this is error . Please correct.
