Synopsis
postgresql-setup MODE_OPTION [--unit=UNIT_NAME] [OPTION...]
Description
Script is aimed to help sysadmin with basic database cluster administration. Usually, "postgresql-setup --initdb" and "postgresql-setup --upgrade" is enough, however there are other options described below.
For more info and howto/when use this script please look at the documentation file /usr/share/doc/postgresql16/README.rpm-dist.
Available operation mode
- --initdb
Initialize new PostgreSQL database cluster. This is usually the first action you perform after PostgreSQL server installation.
- --upgrade
Upgrade database cluster for new major version of PostgreSQL server. See the --upgrade-from option for more info.
Options
- --unit=UNIT_NAME
The UNIT_NAME is used to select proper unit configuration (unit == service or initscript name on non-systemd systems). For example, if you want to work with unit called 'postgresql@com_example.service', you should use 'postgresql@com_example' (without trailing .service string). When no UNIT_NAME is explicitly passed, the 'postgresql' string is used by default.
- --port=PORT
port where the initialized server will listen for connections
- --new-systemd-unit
We dropped this option for security reasons. Nowadays, please use the root-only script /usr/sbin/postgresql-new-systemd-unit.
- --datadir
Dropped with --new-systemd-unit.
- --upgrade-from-unit=UNIT
Select proper unit name to upgrade from. This has similar semantics as --unit option.
- --upgrade-ids
Print list of available IDs of upgrade scenarios to standard output.
- --upgrade-from=ID
Specify id "old" postgresql stack to upgrade from. List of available IDs can be listed by --upgrade-ids. Default is 'postgresql'.
Other options
- --help
show this help
- --version
show version of this package
- --debug
show basic debugging information
Environment
- PGSETUP_INITDB_OPTIONS
Options carried by this variable are passed to subsequent call of `initdb` binary (see man initdb(1)). This variable is used also during 'upgrade' mode because the new cluster is actually re-initialized from the old one.
- PGSETUP_PGUPGRADE_OPTIONS
Options in this variable are passed next to the subsequent call of `pg_upgrade`. For more info about possible options please look at man pg_upgrade(1).
- PGSETUP_DEBUG
Set to '1' if you want to see very verbose shell debugging output.
Built against PostgreSQL version 16.1.
