USAGE_STRING=$"\
Usage: $0 MODE_OPTION [--unit=UNIT_NAME] [OPTION...]
Script is aimed to help sysadmin with basic database cluster administration.
Usually, \"@NAME_BINARYBASE@-setup --initdb\" and \"@NAME_BINARYBASE@-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 $README_DIST.
Available operation mode:
--initdb Create a new PostgreSQL database cluster. This is usually the
first action you perform after PostgreSQL server installation.
--upgrade Upgrade database cluster for new major version of PostgreSQL
server. See the --upgrade-from option for more info.
Options:
--unit=UNIT_NAME The UNIT_NAME is used to select proper systemd's
unit configuration. For example, if you want to
work with unit 'postgresql@com_example.service',
you should use 'postgresql@com_example' (without
trailing .service string). When no UNIT_NAME is
explicitly passed, the 'postgresql' string is used
by default.
--port=PORT port where the server will listen for connections
--datadir=PATH Specify absolute path to DB data directory, only
use with --new-systemd-unit.
--new-systemd-unit Pre-generate system'd configuration in drop-in
directory if the unit is not yet configured,
requires non-default --unit specified and explicit
--datadir and --port.
--upgrade-ids Print list of available IDs of upgrade scenarios to
standard output.
--upgrade-from=ID Specify id \"old\" postgresql stack to upgrade
from. List of available IDs can be listed by
--upgrade-ids. Default is '$option_upgradefrom'.
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."
