This looks like a PostgreSQL "fast shutdown", and occurs precisely 3 seconds after each startup. So it's probably nothing to do with your lakeFS, but rather something is wrong with your PostgreSQL installation. Can you share details about it, including especially how it is running? IIRC there are out of memory conditions that ends up SIGINTing PostgreSQL and causing an exit line this. You might have more information on your system log (so /var/log/messages and/or journalctl). In any case, please see if you can get just PostgreSQL working before proceeding to add on la. Good luck!
