// restoreCmd represents the restore command
var restoreCmd = &cobra.Command{
	Use:   "restore",
	Short: "Restore databases from backup archives",
	Long: `Restore databases from backup archives.

By default, restore runs in dry-run mode showing what would be restored.
Use --confirm flag to perform actual restoration.

Examples:
  # Preview restore (dry-run)
  dbbackup restore single mydb.dump.gz

  # Restore single database
  dbbackup restore single mydb.dump.gz --confirm

  # Restore to different database name
  dbbackup restore single mydb.dump.gz --target mydb_restored --confirm

  # Restore cluster backup
  dbbackup restore cluster cluster_backup_20240101_120000.tar.gz --confirm

  # List backup archives
  dbbackup restore list

var restoreSingleCmd = &cobra.Command{
	Use:   "single [archive-file]",

	Long: `Restore a single database from a backup archive.

Supported formats:
  - PostgreSQL: .dump, .dump.gz, .sql, .sql.gz
  - MySQL: .sql, .sql.gz

Safety features:
  - Dry-run by default (use --confirm to execute)
  - Archive validation before restore
  - Disk space verification
  - Optional database backup before restore

Examples:
  # Preview restore
  dbbackup restore single mydb.dump.gz

  # Restore to original database
  dbbackup restore single mydb.dump.gz --confirm

  # Restore to different database
  dbbackup restore single mydb.dump.gz --target mydb_test --confirm

  # Clean target database before restore
  dbbackup restore single mydb.sql.gz --clean --confirm

  # Create database if it doesn't exist
  dbbackup restore single mydb.sql --create --confirm

This command restores all databases that were backed up together
in a cluster backup operation.

Safety features:
  - Dry-run by default (use --confirm to execute)
  - Archive validation and listing
  - Disk space verification
  - Sequential database restoration

Examples:
  # Preview cluster restore
  dbbackup restore cluster cluster_backup_20240101_120000.tar.gz

  # Restore full cluster
  dbbackup restore cluster cluster_backup_20240101_120000.tar.gz --confirm

// restorePITRCmd performs Point-in-Time Recovery
var restorePITRCmd = &cobra.Command{
	Use:   "pitr",
	Short: "Point-in-Time Recovery (PITR) restore",
	Long: `Restore PostgreSQL database to a specific point in time using WAL archives.

PITR allows restoring to any point in time, not just the backup moment.
Requires a base backup and continuous WAL archives.

Recovery Target Types:
  --target-time      Restore to specific timestamp
  --target-xid       Restore to transaction ID
  --target-lsn       Restore to Log Sequence Number
  --target-name      Restore to named restore point
  --target-immediate Restore to earliest consistent point

Examples:

    --wal-archive /backups/wal/ \\
    --target-time "2024-11-26 12:00:00" \\
