SQL command to clean job queue in pgAdmin 4 I have a Postgres 9.6 installation on a developer pc and a restore seems to have failed. Even after reinstalling (remove Postgres and PgAdmin completely, incl. database and installed new version) the boxes are popping up (even though these tables do not even exist anymore). How to remove these scheduled jobs? Is there an SQL statement to stop these and cleanup the queue? Both jobs are running endless (3000000s+ already).
The file

C:\Users...\AppData\Roaming\pgAdmin\pgadmin4.db

is an sqlite-database. 

Open it (e.g. with https://sqlitebrowser.org/) and delete all rows in the process table. Then restart pgAdmin - the boxes should be gone.
