Error: Cannot restore to existing database name in Railway

Question

Goal
To recover a Railway-managed PostgreSQL database from a point‑in‑time backup and have the restored instance replace the current database without creating a new database name.
Constraints
Railway’s restore operation always creates a new database instance; the dashboard and CLI do not expose an option to overwrite an existing database. The only documented approach is to delete or rename the existing instance before initiating a restore, which introduces potential data loss or naming conflicts.
Uncertainty
There is no official guidance on how to safely perform an in‑place replacement, nor on whether Railway will support such a feature in future releases. Verification of data integrity after restoration relies on external checksum or sample query comparisons, but the platform offers no built‑in verification tool.
Questions

Does Railway plan to add an in‑place restore option that preserves the original database name?
If not, what is the recommended safe sequence for renaming or dropping the current instance before restoration?
Will future backup retention policies affect the ability to restore to a new instance that matches the previous name?

Answer to the question
Railway’s current restore workflow always provisions a new PostgreSQL instance; the dashboard and CLI provide no flag to overwrite an existing database by name.

Possible future change
No public roadmap entry indicates an in‑place restore option. If Railway adds such a feature, the rename‑and‑restore sequence would become unnecessary.

Recommended safe sequence (high‑level)

Take an external backup of the current database (e.g., pg_dump).
Rename or drop the existing database so the original name is free.
Trigger the point‑in‑time restore; Railway will create a new instance with a generated name.
After the restore completes, rename the new instance to the original name.
Update any connection strings that reference the database.

Future retention impact
Backup retention windows (e.g., 7‑day vs. 30‑day) only constrain how far back you can restore. They do not affect your ability to rename the restored instance to the original name afterward.

Diagnostic detail that could change the recommendation
Do you currently have an external backup of the live database? If not, creating one before renaming is essential to avoid data loss.
