User of PostgreSQL database

[mu88]

Dear @flosoft ,

Thank you for providing this super neat repository 🚀

I've a (probably very easy) question regarding the configuration: when running docker top joplinserver-app-1, I can see that the Joplin app itself runs under my user account:

UID                 PID                 PPID                C                   STIME               TTY                 TIME                CMD
myuser              1482907             1482876             0                   17:35               ?                   00:00:00            tini -- yarn start-prod
myuser              1482971             1482907             0                   17:35               ?                   00:00:01            node /opt/yarn-v1.22.19/bin/yarn.js start-prod
myuser              1483056             1482971             0                   17:35               ?                   00:00:00            /bin/sh -c pm2 kill && pm2 start --no-daemon --exp-backoff-restart-delay=1000 dist/app.js
myuser              1483103             1483056             0                   17:35               ?                   00:00:02            /usr/local/bin/node /home/joplin/packages/server/node_modules/.bin/pm2 start --no-daemon --exp-backoff-restart-delay=1000 dist/app.js
myuser              1483116             1483103             3                   17:35               ?                   00:00:21            node /home/joplin/packages/server/dist/app.js

But running docker top joplinserver-db-1 reveals that Joplin's database is running under a totally different user:

UID                 PID                 PPID                C                   STIME               TTY                 TIME                CMD

openhab             1483885             1482900             0                   17:38               ?                   00:00:00            postgres: joplinServer joplinServerDb 172.19.0.3(39222) idle

The user openhab exists on my Raspi and is used for my openHAB instance.

Do you have an idea why Joplin's database runs under a totally different account using your docker-compose.yml?

Thx and take care!
