=head1 NAME

pg_restorecluster - Restore from a pg_backupcluster backup

=head1 SYNOPSIS

B<pg_restorecluster> [I<options>] I<version> I<cluster> I<backup>

=head1 DESCRIPTION

B<pg_restorecluster> restores a PostgreSQL cluster from a backup created by
B<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 I<backup> name passed must end in either B<.basebackup> or B<.dump>;
usually this will be the full path to a backup directory in
C</var/backups/postgresql/version-cluster/> as reported by
B<pg_backupcluster ... list>.

Basebackups are restored as-is. For dumps, B<pg_createcluster> is used to
create a new cluster, and schema and data are restored via B<pg_restore>.

=head1 OPTIONS

=over 4

=item B<-d --datadir> I<DIR>

Use I<DIR> as data directory for the restored cluster (default per
createcluster.conf, by default /var/lib/postgresql/I<version>/I<cluster>).

=item B<-p --port> I<N>

Use port I<N> for restored cluster (default is next free port).

=item B<-s --start>

Start cluster after restoring (default for restore from dump; off for
basebackup restores).

After the cluster has been started, B<ANALYZE> is run on all databases.

=item B<--archive>

Configure cluster for recovery from WAL archive. This sets B<restore_command>
to retrieve WAL files from I<backup>B</../wal>.

=item B<--pitr> I<TIMESTAMP>

=item B<--recovery-target-time> I<TIMESTAMP>

Additionally to setting B<restore_command>, set B<recovery_target_time> to
I<TIMESTAMP> for point-in-time recovery. Also sets
B<recovery_target_action='promote'>.

=item B<--wal-archive> I<DIR>

For archive recovery, read WAL from archive I<DIR> (default is
I<backup>B</../wal>).

=back

=head1 FILES

=over 4

=item /var/backups

Default root directory for cluster backup directories.
