I made a new PostgreSQL database and am trying to add layers/tables to it in QGIS using the DBManager. And I am failing.
However, I can add layers to other PostgreSQL databases that previously existed. I thought it might be some problem in the way I created the new database, using pgAdmin 4, but as far as I can tell the new database is exactly the same as the others.
I tried some workarounds, including creating a new schema in an existing database and couldn't read from that new schema.
