Your Postgres service still has its volume attached, so your data is intact and will be retained for 30 days after trial expiration. To access it, subscribe to a paid plan at your workspace billing page - your services will come back online automatically, and you can run pg_dump yourself. We're not able to temporarily reactivate individual services or provide data exports on suspended accounts.

I don't want to subscribe to paid plan, I just need my data , is there other way to fetch my data without paying you ????

Subscribing to a paid plan is the only way to bring your services back online and access your data. We're not able to temporarily reactivate services, run exports, or provide data through any other path. Your volume data is retained for 30 days, so you have time to subscribe, run your pg_dump, and then cancel if you no longer need the plan.
