Description

When should I change a ParadeDB password?

Rotate credentials after staff turnover, suspected compromise, or on a regular security schedule. ParadeDB reuses PostgreSQL roles, so changing a password is identical to PostgreSQL.

What syntax does ALTER ROLE use?

Use ALTER ROLE role_name WITH PASSWORD 'new_secret' [VALID UNTIL 'YYYY-MM-DD']. The command updates the encrypted password in pg_authid immediately.

How do I change a password for an application user?

1. Connect as a superuser or a role with CREATEROLE.
2.Run the ALTER ROLE statement.
3. Test login with the new credentials.
4. Update environment variables or connection strings used by your app.

Step-by-step example

The ecommerce app stores data in Customers, Orders, Products, and OrderItems.The read-only role report_reader powers dashboards.

-- connect as postgres ALTER ROLE report_reader WITH PASSWORD 'GxY7!vL0$2024' VALID UNTIL '2025-01-01';

The role can now query tables such as SELECT COUNT(*) FROM Orders; with the new password until the specified expiry date.

How do I force a password reset at next login?

ParadeDB follows PostgreSQLs behavior: set VALID UNTIL to a past date.Users must then change the password before reconnecting.

Best practices for ParadeDB password management

• Use long, random strings generated by a secrets manager.
• Add VALID UNTIL for automatic expiry.
• Revoke unused roles with DROP ROLE.
• Store credentials in Vault or AWS Secrets Manager, not in code.

What permissions are required?

Only superusers or roles granted CREATEROLE can alter another roles password. A role can always change its own password.

Can I change multiple passwords in one transaction?

Yes.Wrap several ALTER ROLE commands in a single BEGIN; ... COMMIT; block to maintain atomicity.

Common mistakes to avoid

Missing quotes: Always quote the password string. Unquoted text is interpreted as identifiers.
Forgetting VALID UNTIL: Omitting expiration allows passwords to live forever and increases risk.

Need to roll back?

If a new password breaks your app, simply run ALTER ROLE again with the old secret.No restart is needed.

Ready to automate?

Embed the command in CI/CD or Galaxy SQL editor snippets. Galaxys AI copilot can even generate the exact SQL for you.

How to Change Password in ParadeDB in PostgreSQL Syntax


ALTER ROLE role_name [WITH] 
    PASSWORD 'new_password'
    [VALID UNTIL 'YYYY-MM-DD HH:MI:SS']

-- Alias
ALTER USER role_name [WITH] PASSWORD 'new_password';

-- Example in ecommerce context
ALTER ROLE app_service WITH PASSWORD 'S3cur3@123' VALID UNTIL '2025-12-31';

Common Mistakes

Omitting quotes around the new password leads to ERROR: syntax error at or near identifier. Always wrap the password inside single quotes.
Running ALTER ROLE without superuser or CREATEROLE privileges fails with ERROR: permission denied. Connect as an admin role or grant CREATEROLE first.
