PubSub v 3.2.0 adds a new procedure TigPubSubGetNodeMeta which supports PubSub metadata retrieval while conducting a disco#info query on nodes.
You will need to upgrade your database if you are not using v3.2.0 schema. Tigase will report being unable to load PubSub component if you do not have this schema version.
The MySQL schema can be found Here.
The Derby schema can be found Here.
The PostGRESQL schema can be found Here.

The same files are also included in all distributions of v8.0.0 in [tigaseroot]/database/ . All changes to database schema are meant to be backward compatible.
