postgresql-upgrade - manual page for postgresql-upgrade 8.9~dev

SYNOPSIS

postgresql-upgrade [--upgrade-from=ID] DATADIR

DESCRIPTION

Wrapper script for pg_upgrade. It has pre-configured pg_upgrade options and environment variables.

OPTIONS

Print list of available IDs of upgrade scenarios to standard output.
Specify id "old" postgresql stack to upgrade from. List of available IDs can be listed by --upgrade-ids. Default is 'postgresql'.

Other options:

show version of this package

ENVIRONMENT

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.
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).

Built against PostgreSQL version 16.1.
