MULTIPLE POSTMASTERS ------------------------------------------------------------------------------- The postgresql-server package contains a systemd "unit" files @pkgname@.service -and @pkgname@@.service.

The first file is used solely to start the default +PostgreSQL server. The second one is designed to allow instantiating +additional PostgreSQL servers on same machine. As an example, let us create a secondary PostgreSQL service called, creatively enough, 'postgresql@secondary'. Here are the steps: -1) Create a file named @PKGCONFIG_DIR@/postgresql@secondary - and this line in it: - PGDATA=/path/to/data/directory - Replace the "/path/to/data/directory" with appropriate settings that - don't conflict with any other PostgreSQL setup. -2) Create the target PGDATA directory, making sure that its parent - directories have appropriate ownership and permissions. -3) Initdb the target PGDATA with - '@pkgname@-setup --initdb --unit @pkgname@@secondary --port NNNN'. - Substitute the NNNN with port number of your decision (make sure that - this port is not used by any other service). -4) Edit postgresql.conf in the target PGDATA to change settings as needed. -5) Start the new service with this command: +1) Run the following command to create the necessary configuration and + to initialize the new database cluster: + @pkgname@-setup --initdb \ + --unit postgresql@secondary \ + --new-systemd-unit \ + --datadir /path/to/data/directory \ + --port NNNN + Replace the "/path/to/data/directory" path and NNNN port with + appropriate settings that don't conflict with any other PostgreSQL + setup.
