Suddenly the time required to backup with pg_dump increased suddenly drastically ( + 20min on a backuptime of 2 hours ) no comparable increase of data which could explain the behaviour.
We want to dig into it but we lack a detailled pg_dump log. We used verbose mode but unfortunately this lacks a date time stamp. No changes on the server neither.
Postgres: version 11.13 pg_dump is running on the same machine as Postgres and no changes have been made to the configuration
