Our PostgreSQL database ran out of disk space during a bulk UPDATE operation (updating ~2,700 rows with JSONB data). The database crashed mid-checkpoint and is now stuck in a crash-recovery loop:

1. PostgreSQL starts and successfully replays WAL (redo done at 0/3DFFFF28)
2. Fails when trying to write checkpoint: FATAL: could not write to file "pg_wal/xlogtemp.30": No space left on device
3. Shuts down and restarts, repeating the cycle

We increased the volume size via the Railway dashboard, but the change doesn't seem to be taking effect - still getting "No space left on device" after redeploy.

Solutions greatly appreciated!!
