# Known Bugs and Issues

## 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](/system/services#/prometheus-sql-exporter.service).

## OmniDB

  • OmniDB does not use PAM authentication.

## Portal

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

## RedHat / CentOS

  • pgAdmin4 does not work when SELinux is enabled.

  • shellinabox does not work when SELinux is enabled.
