  • A dedicated replication user and replication slot are created
  • Source is restarted via Coolify API if configuration changes require it
  • A new PostgreSQL database is created on the target Coolify instance
  • pg_basebackup copies all data from source to target
  • Target is configured as a hot standby with standby.signal
  • Replication status is verified automatically
  • The replica is registered in Synchro and linked to the source
