What happens after 7 days?+

You stay on Pro at $24.99 a month. Cancel before day 7 and you are not charged. The free catalog stays either way.

What does Pro add?+

The second test on the error, the runbook SQL, the taught lesson, the Deep Internals body, the interview answer, and the worldwide PostgreSQL Jobs list. Every error page, every outline, ten current jobs, the glossary, and the GUCs stay free.

Why would I pay yearly?+

You pay $199 once. That’s two months free. No trial — Pro starts today.

Can I cancel?+

Yes. Before day 7, nothing is charged. After that, from your account. Monthly stops at the end of the period. Annual runs until renewal.
