This adds a 'MOVE' sub-command to ALTER TABLESPACE which allows moving sets of objects from one tablespace to another. This can be extremely handy and avoids a lot of error-prone scripting. ALTER TABLESPACE ... MOVE will only move objects the user owns, will notify the user if no objects were found, and can be used to move ALL objects or specific types of objects (TABLES, INDEXES, or MATERIALIZED VIEWS).
