Frequently Asked Questions
Everything you need to know about MQZZ.DB, quotas, and PostgreSQL connections.
Is the 5 GB database really free forever?
Yes. Every registered user receives a free 5 GB storage allocation for up to 3 PostgreSQL databases. There are no surprise renewal charges and no credit card required to register.
Can I connect directly using psql, DBeaver, or pgAdmin?
Yes! You are provided standard host, port (5432), username, password, and connection string URI. You can connect from any desktop database client or external server using SSL.
Why is SSL required for connections?
Security is mandatory on MQZZ.DB. Requiring SSL (`sslmode=require`) encrypts the connection between your application and our PostgreSQL servers, ensuring your passwords and sensitive customer data cannot be intercepted in transit.
What happens if my database exceeds 5 GB?
When your database reaches 5 GB, write operations (INSERT, CREATE, UPDATE) are temporarily paused to protect the cluster integrity. Your read queries (SELECT) and database backups will continue to work without disruption until you clean up data or upgrade your quota.
Can other users on the platform see my database?
No. Each database is assigned a unique, isolated user role. Permissions on other databases and the PostgreSQL public catalog are strictly revoked. Users have zero visibility or access to any database they do not own.
Are backups included?
Yes. You can create encrypted point-in-time SQL backups anytime from your dashboard or via the REST API. Backups can be downloaded or restored with a single click.
