# 7. Known Bugs and Issues

## 7.1. PostgreSQL

- The `prometheus-sql-exporter` monitoring agent is permanently keeping connections open to all databases, which prevents `DROP DATABASE` from working. To drop databases, stop `prometheus-sql-exporter` first. This is possible via the web interface Cockpit: services#/prometheus-sql-exporter.service.

## 7.2. pgadmin4

- pgadmin4 does not use PAM authentication.
- By default, pgadmin4 does not show local databases.

## 7.3. Portal

- A direct relogin after a logout does not work. Reloading the page is necessary.

## 7.4. RedHat / CentOS

- pgAdmin4 does not work when SELinux is enabled.
- shellinabox does not work when SELinux is enabled.
