Same issue as solved threads by @brody: - "PostgreSQL crash loop after volume resize — resize not applied to filesystem" (11 days ago, solved same day) - "Postgres crash loop: No space left on device after Live Resize" (4 days ago, solved) Live resize from 500MB to 5GB did not apply to filesystem. PostgreSQL crash-loops with: FATAL: could not write to file "pg_wal/xlogtemp.30": No space left on device WAL recovery completes successfully every time — no data corruption. Please apply the same fix (correct the volume resize and redeploy).
