What does “restore backup ParadeDB” accomplish?

It rebuilds all tables, indexes, extensions, and data in a target database from a ParadeDB backup file (.dump or .sql). The operation is transaction-safe, letting you fully recover or clone environments.

Which tools can I use?

Use pg_restore for custom/tar backups and psql for plain SQL files. Both honor ParadeDB objects because ParadeDB is extension-compatible with PostgreSQL.

How do I prepare the target database?

Create the empty database and install ParadeDB before restoring.Example: CREATE DATABASE shop_clone; then CREATE EXTENSION paradedb;.

What is the exact restore syntax?

See the next section for the full command reference, including options for roles, schemas, and parallelism.

Step-by-step restore walkthrough

1. Copy shop.dump to the server.
2. Run pg_restore with the --clean and --create flags if you want a one-shot rebuild.
3.Verify counts with simple SELECTs on Customers, Orders, and Products.

Best practices for ParadeDB restores

• Restore into a staging DB first.
• Use --jobs to speed up large ecommerce datasets.
• Always enable --if-exists to avoid errors if objects are missing.

Common mistakes to avoid

Skipping the ParadeDB extension or forgetting to drop active connections will abort the restore. Details follow after the syntax block.

-- Verify restored data integrity for ecommerce shop
SELECT o.id,
       c.name AS customer_name,
       o.total_amount,
       SUM(oi.quantity * p.price) AS recomputed_total
FROM "Orders" o
JOIN "Customers" c ON c.id = o.customer_id
JOIN "OrderItems" oi ON oi.order_id = o.id
JOIN "Products"    p ON p.id  = oi.product_id
GROUP BY o.id, c.name, o.total_amount
HAVING SUM(oi.quantity * p.price) <> o.total_amount;

How to Restore a ParadeDB Backup in PostgreSQL Syntax


# Custom or tar backup created with pg_dump -Fc
pg_restore \
  --dbname=shop_clone          # Target DB
  --username=postgres          # Superuser or owner
  --host=localhost             # Server
  --port=5432                  # Port
  --jobs=4                     # Parallel workers
  --clean --if-exists          # Drop objects before re-create
  --no-owner                   # Restore with current role
  --schema=public              # Optional: specific schema
  /backups/shop.dump

# Plain SQL backup
psql -U postgres -h localhost -d shop_clone -f /backups/shop.sql

# Post-restore verification in ecommerce context
SELECT COUNT(*) FROM "Customers";
SELECT SUM(total_amount) FROM "Orders";

Common Mistakes

Mistake: Restoring before installing ParadeDB. Why wrong: objects referencing the extension fail. Fix: run `CREATE EXTENSION paradedb;` in the target database first.
Mistake: Active connections on the target database. Why wrong: `pg_restore --clean` cannot drop objects in use. Fix: `SELECT pg_terminate_backend(pid) FROM pg_stat_activity WHERE datname='shop_clone' AND pid <> pg_backend_pid();`
