Description

What does “export schema” do in ParadeDB?

ParadeDB wraps pg_dump so you can save one PostgreSQL schema—tables, views, functions, triggers, and grants—into a readable .sql file. Only DDL is extracted; no data unless you ask for it.

Which flags are required?

Provide the database, schema, and output path. ParadeDB forwards them to pg_dump, adding connection pooling and progress output.

How do I export the ecommerce schema?

Run the command from your terminal or Galaxy SQL editor.It creates ecommerce_schema.sql containing CREATE statements for Customers, Orders, Products, and OrderItems.

How can I include data as well?

Add the --data switch. ParadeDB pipes both structure and INSERT commands, useful for quick cloning of small schemas.

What privileges are needed?

Your role needs CONNECT on the database and USAGE on the schema plus SELECT on all objects. Lack of any privilege aborts the export.

Best practice: keep schema-only dumps in version control

Commit the .sql file to Git.Teammates can track migrations, review DDL changes, and restore environments reliably.

Can I restore to a different database?

Yes. Feed the generated file into psql on any server running an equal or newer PostgreSQL version, with ParadeDB installed if it uses Parade-specific types.

Key takeaway

Exporting a schema with ParadeDB is a one-line, idempotent operation that simplifies backups, reviews, and CI deployments.

Common Mistakes

Frequently Asked Questions (FAQs)

Does ParadeDB need to be installed on the target server for restore?

Only if your dump uses ParadeDB-specific types. Pure SQL objects restore fine on standard PostgreSQL.

Can I export multiple schemas at once?

Yes. Pass the --schema flag multiple times or use a comma-separated list: --schema public --schema ecommerce.

How do I schedule automatic schema exports?

Use cron plus ParadeDB CLI, or Galaxy’s upcoming workflows, to run the command nightly and push to object storage.
