I tried the command you suggested, and it shows that data directory status as "DOWN". Yet when I ask pg_ctlcluster for it's status it says the server is running. What does this mean? root@d11:/var/tmp/myapp# pg_lsclusters Ver Cluster Port Status Owner Data directory Log file 13 main 5432 down postgres /var/lib/postgresql/13/main /var/log/postgresql/postgresql-13-main.log 15 main 5433 down postgres /var/lib/postgresql/15/main /var/log/postgresql/postgresql-15-main.log root@d11:/var/tmp/myapp# sudo -u postgres /usr/bin/pg_ctlcluster 15 main status -- -D /var/lib/postgresql/13/main pg_ctl: server is running (PID: 2701882) /usr/lib/postgresql/15/bin/postgres "-D" "/var/lib/postgresql/13/main" "-c" "config_file=/etc/postgresql/15/main/postgresql.conf" root@d11:/var/tmp/myapp# -----Original Message----- From: Adrian Klaver [mailto:adrian.klaver@xxxxxxxxxxx] Sent: Friday, April 7, 2023 6:47 PM To: Telium Technical Support <support@xxxxxxxxx>; pgsql-general@xxxxxxxxxxxxxxxxxxxx Subject: Re: pg_ctlcluster is not stopping cluster On 4/7/23 15:27, Telium Technical Support wrote: > I am string to stop my PostgreSQL (on debian 11) server using the > following command > > root@d11:/# sudo -u postgres /usr/bin/pg_ctlcluster 15 main stop -- -m > fast -D /var/lib/postgresql/13/main > > Notice: extra pg_ctl/postgres options given, bypassing systemctl for > stop operation > > pg_ctl: PID file "/var/lib/postgresql/13/main/postmaster.pid" does not > exist > > Is server running? > > The notice is correct, the is no such postmaster.pid file in that > directory, but yes the service is running.

Yes that this: sudo -u postgres /usr/bin/pg_ctlcluster 15 main stop -- -m fast -D /var/lib/postgresql/13/main is not correct. First do: pg_lsclusters to determine what is actually running. Then do sudo -u postgres /usr/bin/pg_ctlcluster <version> main stop -- -m fast -D /var/lib/postgresql/13/main stop -m fast for whatever version is running. > -- Adrian Klaver adrian.klaver@xxxxxxxxxxx
