When I try to edit data in phppgadmin, no matter which table or row, I always got following notification 'No unique identifier for this row.
' and nothing is changed/saved.
The user I'm logged in has full privileges on the database and all tables in database have primary keys.
I'm using phppgadmin for many years and I've never had such a problem before. I should mention, this is a fresh installation of Ubuntu.
Does anyone has a clue what happening here and how to solve this issue? Thanks
EDIT
Even downgrading postgresql to version 13 didn't help.
