Database errors following installation - Joomla! Forum - community, help and support

is there problem sql in installation package?

immediately folowing new installation of 1.0.4 new, empty database, phpmyadmin reports these errors in database:

problems indexes of table `jos_categories`
   more 1 index key created column `section`
problems indexes of table `jos_core_acl_aro_groups`
   more 1 index key created column `parent_id`
problems indexes of table `jos_core_acl_aro_sections`
   more 1 unique key created column `value`
   more 1 index key created column `hidden`

i performed test shown above because live site has more errors, shown here:

problems indexes of table `jos_categories`
   more 1 index key created column `section`
problems indexes of table `jos_core_acl_aro`
   more 1 unique key created column `section_value`
   more 1 index key created column `hidden`
problems indexes of table `jos_core_acl_aro_groups`
   more 1 index key created column `parent_id`
problems indexes of table `jos_core_acl_aro_sections`
   more 1 unique key created column `value`
   more 1 index key created column `hidden`
problems indexes of table `jos_sb_messages`
   primary , index keys should not both set column `id`
problems indexes of table `jos_sb_moderation`
   primary , index keys should not both set column `catid`

one more thing. when open phpmyadmin perform these checks, see warning message: "the mbstring php extension not found , seem using multibyte charset. without mbstring extension phpmyadmin unable split strings correctly , may result in unexpected results."
