I have not attempted this particular course yet so I’m not sure how much help I could be. (I’ve also only used PgAdmin as a GUI w/PostgreSQL).
If you’ve googled the error messages and determined that you should change your pw authentication settings, then I suggest trying it. (you can always change it back if it doesn’t work).
I found this: https://github.com/dbeaver/dbeaver/issues/2122
And the PostgreSQL documentation on authentication methods might help:
It says that it saved the file but I find no file. However, though I am not sure this is related, when I open pgAdmin I see the same databases created with Postbird and from there I can export the tables I created.
In a way or another, I manage to do what I need to for now but I still wonder what is wrong…
This post was first open in Dec 2020.
I joined amonth ago (May 2021) and cannot find a suitable solution to this problem.
I already uninstalled/re-installed postbird/postgres, used different versions and can’t use that baseball database at all.
After looking into other forum topics for the same issue, I see no clear answer on how to resolve this “method 10 is not supported”.
I also had this issue. What I did was installing the listed alternative, pgAdmin 4, to export my Postgres database.
Although the interface is more cluttered, you just have to right click on database and chose “Backup” and “Restore”.
