When using postgres as the storage plugin and sqllitememory as the readings plugin, the following error appears in the logs periodically:
ERROR: Can't statfs /usr/local/fledge/data/fledge.db, No such file or directory. Disk space monitoring is disabled
The file /usr/local/fledge/data/fledge.db does not exist, likely because the default SQLite plugin is not in use. This suggests that the disk space monitoring feature does not work properly in that configuration.
