Oh that's different - the pg_stat_activity shows queries running in every database on your cluster. Tom Lane The current column ordering can be rationalized to some extent as 1. identity info (user id, db id, application name) 2. current query info 3. session info (backend start time, client addr/port) Putting backend_start first doesn't fit at all with that view of the grouping. You can also limit pgBadger to only report err. Waiting to read or update transaction disabled: This fastpath Enter the PostgreSQL command shell.
