Hello,

My TimescaleDB volume shows 4GB usage in the Railway dashboard, but Postgres reports only 401MB total. There's a discrepancy of ~3.6GB that I cannot account for.

Here are the metrics from within Postgres:

DATABASE SIZE:

- Database: 113 MB

- WAL logs: 288 MB

- Total visible from Postgres: 401 MB

TOP 10 TABLES BY SIZE:

1. compress_hyper_6_4_chunk: 100 MB

2. option_spreads: 1.6 MB

3. fetch_jobs: 112 KB

4. options_snapshots: 80 KB

(All other tables < 100 KB)

TIMESCALEDB INFO:

- 1 hypertable: options_snapshots (compressed, 1 chunk)

- Total tablespace size: 138 MB

QUESTION:

Where are the remaining ~3.6GB located? Is this:

1. Provisioned disk space vs actual usage?

2. TimescaleDB internal files not visible from SQL?

3. System backups/snapshots?

4. Old WAL segments or temp files?

Can you help identify what's consuming the disk space?

Thanks!
