How to Design Schema ParadeDB in PostgreSQL

How do I create and manage a ParadeDB schema in PostgreSQL?

CREATE SCHEMA groups tables, views, and functions under a named namespace, letting you organize ParadeDB objects cleanly.

Why create a ParadeDB schema instead of using public?

Namespaces prevent name clashes, simplify permissions, and clarify ownership. Creating a dedicated paradedb schema keeps Parade-specific tables separate from application or reporting objects.

How do I create the ParadeDB schema?

Run CREATE SCHEMA once, ideally during database provisioning. Use IF NOT EXISTS to avoid errors on subsequent deployments.

Can I assign an owner at creation time?

Yes—add AUTHORIZATION role_name. The role immediately owns every object created inside the schema unless overridden.

What if I need to create it under a different database?

Change connection string or run CREATE SCHEMA within the target database using \c database_name in psql.

How do I add ecommerce tables inside ParadeDB?

Prefix table names with paradedb. or set SET search_path TO paradedb. You can encapsulate common ecommerce entities—Customers, Orders, Products, and OrderItems—while leaving operational tables elsewhere.

What privileges should I grant?

After creation, execute GRANT USAGE ON SCHEMA paradedb TO readonly_role; and GRANT ALL ON SCHEMA paradedb TO app_role; to control access.

Best practices for ParadeDB schema design?

Keep related objects together, document them with COMMENT, limit implicit privileges, version SQL in migrations, and avoid cross-schema foreign keys unless required.

What are common mistakes and how to avoid them?

Skipping IF NOT EXISTS breaks idempotent deploys. Forgetting to set the search path causes objects to land in public. See details below.

Why How to Design Schema ParadeDB in PostgreSQL is important

How to Design Schema ParadeDB in PostgreSQL Example Usage


-- Idempotently create ParadeDB schema and tables
CREATE SCHEMA IF NOT EXISTS paradedb AUTHORIZATION ecommerce_admin;

SET search_path TO paradedb;

CREATE TABLE IF NOT EXISTS Products (
    id     SERIAL PRIMARY KEY,
    name   TEXT NOT NULL,
    price  NUMERIC(10,2) NOT NULL,
    stock  INT DEFAULT 0
);

GRANT SELECT ON ALL TABLES IN SCHEMA paradedb TO reporting_role;

How to Design Schema ParadeDB in PostgreSQL Syntax


CREATE SCHEMA [IF NOT EXISTS] paradedb
    [AUTHORIZATION role_name]
    [COMMENT IS 'optional description'];

-- Example with ecommerce context
CREATE SCHEMA IF NOT EXISTS paradedb AUTHORIZATION ecommerce_admin;

-- Create tables inside the schema
SET search_path TO paradedb;
CREATE TABLE Customers (
    id            SERIAL PRIMARY KEY,
    name          TEXT NOT NULL,
    email         TEXT UNIQUE NOT NULL,
    created_at    TIMESTAMPTZ DEFAULT NOW()
);
CREATE TABLE Orders (
    id            SERIAL PRIMARY KEY,
    customer_id   INT REFERENCES Customers(id),
    order_date    DATE NOT NULL,
    total_amount  NUMERIC(12,2) NOT NULL
);
CREATE TABLE Products (
    id     SERIAL PRIMARY KEY,
    name   TEXT NOT NULL,
    price  NUMERIC(10,2) NOT NULL,
    stock  INT DEFAULT 0
);
CREATE TABLE OrderItems (
    id         SERIAL PRIMARY KEY,
    order_id   INT REFERENCES Orders(id),
    product_id INT REFERENCES Products(id),
    quantity   INT NOT NULL
);

Common Mistakes

Omitting IF NOT EXISTS: Redeploying migration scripts without the clause raises “schema already exists.” Fix by adding IF NOT EXISTS to CREATE SCHEMA for idempotency.
Leaving search_path unchanged: Objects unintentionally land in the public schema. Always run SET search_path TO paradedb or fully qualify names during object creation.
