I'd guess so. Since using an autoincrement requires that the PK be in use, and that PK is not in gold, that would suggest that phpmyadmin uses gold to mark what is not a pk.
I haven't used phpmyadmin in a long long time. You could simply issue a SHOW CREATE TABLE yourtablename query and it will give you the text required to create it. That would indicate all your keys as well.
