Hi, my PostgreSQL service on Railway is stuck in a crash

loop due to a full disk. The logs show:

FATAL: could not write to file "pg_wal/xlogtemp.39": No

space left on device

Postgres can't complete WAL recovery on startup because it

runs out of space immediately. I've increased the volume to

5GB but it still crashes before I can connect and run any

cleanup queries. I need help either mounting the volume

directly to delete data, or another way to get the database

running long enough to clear some space.
