All PostgreSQL Bloat services of a host crashed with KeyError: 'tbloat' if the postgres_bloat section of the agent output did not start with its column header line. The agent plug-in prints this header only together with the bloat data of the first database, so it can be missing if no data is returned for that database.

The services now go to UNKNOWN with the summary Cannot evaluate bloat data: column 'tbloat' is missing in the agent output.
