How to disable automatic startup of one of the PostgreSQL 10 instances?

Question

linux

There is a Debian 9.0 server running PostgreSQL 10 version.
Launched 10 instances on various ports.
It is necessary that after restarting the server, 2 instances would not start automatically.

Attempts to do it by analogy with a single postgresql server (service) were unsuccessful.

sudo systemctl disable [email protected]

Answer 1

Debian/ubuntu specific.
Change /etc/postgresql/version/cluster_name/start.conf
auto (default) - automatic start
manual - manually
If you are using systemd, after changing the file, run systemctl daemon-reload
