PostgreSQL Daemon Not Working

I'm having trouble creating a successful daemon. Before PostgreSQL went to naming their folders with an @ symbol, I had a working daemon, but now something, somewhere has changed that I can't figure out. If I run: sudo -u _systemuser /opt/homebrew/opt/postgresql@14/bin/postgres -D /opt/homebrew/var/postgresql@14 PostgreSQL starts fine. However this plist doesn't work: Label homebrew.mxcl.postgresql RunAtLoad GroupName _systemuser UserName _systemuser ProgramArguments /opt/homebrew/bin/postgres -D /opt/homebrew/var/postgres In LaunchControl, it says "This job has failed for no apparent reason." So if I enable logging: Label homebrew.mxcl.postgresql14 RunAtLoad GroupName _systemuser UserName _systemuser ProgramArguments /opt/homebrew/opt/postgresql@14/bin/postgres -D /opt/homebrew/var/postgres@14 StandardErrorPath /opt/homebrew/var/log/postgresql@14.log StandardOutPath /opt/homebrew/var/log/postgresql@14.log I get the error "User _systemuser cannot write to the file: "file:///opt/homebrew/var/log/postgresql@14.log"" I've changed the permissions to those folders with: sudo chown -R _systemuser /opt/homebrew/var/postgresql@14 sudo chgrp -R _systemuser /opt/homebrew/var/postgresql@14 However, using this logging plist does evoke a new error in LaunchControl: 2024-12-26 11:06:02.649106 Service could not initialize: posix_spawn(/opt/homebrew/opt/postgresql@14/bin/postgres), error 0xd - Permission denied But as I said at the start, PostgreSQL starts up fine from CLI. Stumped. Any ideas on what might be the problem?
