AFAICS ALTER TABLE SET STORAGE means ALTER TABLE ... ALTER COLUMN SET
STORAGE. There is no ALTER TABLE SET STORAGE per table. It seems you are
confusing with ALTER TABLE SET (storage_parameter = value, ...).
Perhaps, we should use the complete command (ALTER TABLE tablename ALTER
COLUMN colname SET STORAGE storagetype) or link ALTER TABLE to avoid
confusion.
