Right, the systemd example in the docs is not using pg_ctl.
But, it should be easily possible to have:
- pg_ctl call postgres with a padded argv0
- postgres call itself with padding, if it wasn't called with that already
This way, there would be no additional exec call when started through
pg_ctl, but one more call when started directly.
Best,
