SQL errors in upgrade

[Dee P.]

Just upgraded to 1.4.2.5. On install, it said that the upgrade was successful, but picked up 2 sql errors. Before going to much further, should I try again or not worry about it? The log is 3 pages long, but the first bit is:

SET NAMES 'utf8'

ALTER TABLE `ps_tab_lang` MODIFY `id_lang` int(10) unsigned NOT NULL AFTER `id_tab`

ALTER TABLE `ps_carrier` ADD `is_free` tinyint(1) unsigned NOT NULL DEFAULT '0' AFTER `is_module`

(1060) Duplicate column name 'is_free'
UPDATE `ps_address_format` SET `format`=REPLACE(REPLACE(`format`, 'state_iso', 'State:name'), 'country', 'Country:name')

ALTER TABLE `ps_orders` ADD INDEX `date_add`(`date_add`)

(1061) Duplicate key name 'date_add'
/* PHP:update_module_followup(); */

Downloaded it a second time and got the same errors.

I also got the following SQL errors:

UPDATE `ps_address_format` SET `format`=REPLACE(REPLACE(`format`, 'state_iso', 'State:name'), 'country', 'Country:name')

(1146) Table 'dermalse_final2.ps_address_format' doesn't exist

UPDATE `ps_address_format` SET `format`=REPLACE(`format`, 'state', 'State:name')

(1146) Table 'dermalse_final2.ps_address_format' doesn't exist

Everything seems to be working OK. Is this something to worry about?
