Hi,

Just tried postmoogle and noticed that the Docker part in README is missing info about data-volume.

If /data inside container isn't writable, postmoogle will throw a misleading error:

postmoogle-1  | FTL app/cmd/postmoogle/main.go:125 > cannot initialize matrix bot error="failed to upgrade client state store: failed to check if version table is up to date: unable to open database file: out of memory (14)"

I'm not sure if /data contains state that should be stored, but I solved this with a RW bind mount that had the appropriate owner.
