The pg command should run as nonroot,also the stolon program should run as nonroot,so how can I debug the program whith dlv?When I use sudo -u postgres dlv to debug the program , it's could not run normal.If I use root to run the program,returns this error "cannot get instance state: exit status 1" when to execute the cmd "pc_ctl status -D /data/stolon_data/postgres".
