Hi, I’m on the Pro plan and I just upgraded my PostgreSQL database from 5 GB to 20 GB. Right after the upgrade, the database crashed and now it won’t start.

Here’s the error I get in the logs:

PANIC: replication checkpoint has wrong magic 0 instead of 307747550
startup process was terminated by signal 6: Aborted
aborting startup due to startup process failure

Everything was working fine before the upgrade. The database contains important data I imported from my local environment and now it’s completely inaccessible.

Can you please:
1. Check what caused this during the upgrade?
2. Let me know if there’s any way to recover the data?
3. Suggest how to fix or reset the database if needed?

Thanks a lot!
