Postgres logs not present in ElasticSearch
As a result of https://gitlab.com/gitlab-com/gl-security/secops/operations/-/issues/733#note_304744521, we stopped ingesting postgres logs into ElasticSearch and therefore we don't have any postgres logs available in Kibana: pubsub-postgres-inf-gprd*
only contains logs from pgbouncer.
This issue is about finding a way to re-enable ingestion of logs into ElasticSearch.
