postgresql11-server @11.10 startupitem don't start

[yesyves]

MacOS 10.11.6

sudo port load postgresql11-server
--->  Loading startupitem 'postgresql11-server' for postgresql11-server

Seems to work as expected but no postgres process running after command or after reboot and no trace of activity in the log file

Doing the wrapper command manually works as expected :

sudo su postgres -c '/opt/local/lib/postgresql11/bin/pg_ctl -D /opt/local/var/db/postgresql11/defaultdb -l /opt/local/var/log/postgresql11/postgres.log start'
waiting for server to start.... done
server started

I made a few tests with the ports installed :

1. port load foo
2. ps acx | grep foo

mpstats does not seems to work

rsync does not seem to work

dbus seems to work (dbus-daemon is showing in the processes)
