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. I can confirm it's running with: root@d11:/# 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" So why is my stop command being ignored? (I tried without the -m fast option but no change, and I'd like to keep that for other reasons). I confirmed with 'ps ax' that postgresql 15 is running, despite the directory suggesting it might be 13. Coincidentally, there is a postmaster.pid file in a directory OTHER than the data directory: /var/lib/postgresql/15/main/postmaster.pid (and notice the 15). Is this a clue? |
