It looks like you had logged in using oauth and then explicitly forbidden yourself from doing so in the future. That's clearly something we should disallow since it creates a catch-22, but we don't now.
I've re-enable oauth for the account so you should now be able to log in with that one. Please confirm that that is working. If you still want it removed and converted to not use oauth later, we can do that as a separate step.
Problems: 1. When trying GitHub/Google OAuth login on commitfest.postgresql.org, error shows: "OAuth login not allowed to this account." 2. This account was created via third-party OAuth, so self-service password reset page rejects password change, prompt: "This account cannot change password as it's connected to a third party login site." 3. I can neither log in via OAuth nor create a native password to log in with username/password.
Requests: 1. Detach all third-party OAuth bindings from my account; 2. Generate a temporary password for my native account, or enable me to set a new password via reset link; 3. Restore normal username/password login access for CommitFest.
If needed, I can provide patch links I submitted before to verify account ownership. Thanks a lot!
