Module update issue (SQL) 5.x-1.4 to 6.x-1.x-dev

I got this issue when upgrading:
ALTER TABLE {audio} ADD `remote_size` VARCHAR(255) NOT NULL DEFAULT ''
Failed: ALTER TABLE {audio} ADD `remote_size` MEDIUMINT NOT NULL DEFAULT 0

Update #6001
Failed: ALTER TABLE {audio_image} DROP PRIMARY KEY
Failed: ALTER TABLE {audio_image} ADD PRIMARY KEY (vid, fid)

Have made alterations to DB and seems to be functioning ok.
