Changing user for supervisor - error CRIT Set uid to user

I changed user for supervisor from root to non-root called dev. All is good, supervisor is running as dev:

me@server$ ps aux | grep supervisor
dev  25230  0.2  1.0  60404 21392 ?        Ss   21:42   0:00 /usr/bin/python /usr/bin/supervisord -n -c /etc/supervisor/supervisord.conf

...but logs shows this message:

Nov 15 21:45:00 server supervisord: 2019-11-15 21:45:00,880 CRIT Set uid to user 1003

This is uid for user dev:

me@server$ id dev
uid=1003(dev) gid=1000(ww) groups=1000(ww)

What does it mean? How should I change uid when user with this uid is already running supervisor?
