Hi. I am trying to restore the forum using the downloaded backup, but getting the following error:
ERROR: could not create unique index "index_users_on_username_lower"DETAIL: Key (username_lower)=(alex) is duplicated.
After looking into the usernames manually, I can see that there are two users with a name Alex - one with uppercase while another one with lowercase. Looks like it is perceived as a duplicate record. Any suggestion on how to resolve the issue would be highly appreciated.
