I try to use pgAdmin 4 on Windows 10 with PostgreSQL 12.1, but it is quite unusable.The application starts, I enter the master password, I can connect to the server and open the entry for one of my databases in the tree on the left side of the pgAdmin window. So far everything looks normal. Then I try to do something with that database - look at a table definition, look at data, start a backup. Now the cursor usually changes to a rotating circle, or I click a button and nothing happens. And this state lasts, sometimes for hours, till I close the pgAdmin window. Sometimes I can do one or two actions with the database before everything hangs - but most of the time even that is impossible. This state of affairs is new, possibly since the update to Version 12 of PostgreSQL. Before, I usually could do more and pgAdmin stopped responding later.
My browser is Firefox, but I just tried with Edge - same thing.
I'm using the EDB installer and the pgAdmin version contained in that package (4.15 at the moment, I think). The PostgreSQL server and pgAdmin run on the same machine.
