PG_RESTORECLUSTER(1) Debian PostgreSQL infrastructure PG_RESTORECLUSTER(1)
NAME
pg_restorecluster - Restore from a pg_backupcluster backup
SYNOPSIS
pg_restorecluster [options] version cluster backup
DESCRIPTION
pg_restorecluster restores a PostgreSQL cluster from a backup created by
pg_backupcluster. The cluster will be newly created in the system using
the name provided on the command line; this allows renaming a cluster on
restore. The restored cluster configuration will be updated to reflect
the new name and location.
The backup name passed must end in either .basebackup or .dump; usually
this will be the full path to a backup directory in
/var/backups/postgresql/version-cluster/ as reported by pg_backupcluster
... list.
Basebackups are restored as-is. For dumps, pg_createcluster is used to
create a new cluster, and schema and data are restored via pg_restore.
OPTIONS
-d --datadir DIR
Use DIR as data directory for the restored cluster (default per
createcluster.conf, by default /var/lib/postgresql/version/cluster).
-p --port N
Use port N for restored cluster (default is next free port).
-s --start
Start cluster after restoring (default for restore from dump; off
for basebackup restores).
After the cluster has been started, ANALYZE is run on all databases.
--archive
Configure cluster for recovery from WAL archive. This sets
restore_command to retrieve WAL files from backup/../wal.
--pitr TIMESTAMP
--recovery-target-time TIMESTAMP
Additionally to setting restore_command, set recovery_target_time to
TIMESTAMP for point-in-time recovery. Also sets
recovery_target_action='promote'.
--wal-archive DIR
For archive recovery, read WAL from archive DIR (default is
backup/../wal).
FILES
/var/backups
Default root directory for cluster backup directories.
See pg_backupcluster(1) for a description of files.
