Having some really frustrating problems with our postgres database for this mastodon instance. When running out database dump (backup) scripts we hit a fatal error relating to missing or corrupted toast values:
`Dumping the contents of table "status_edits" failed: ... ERROR: missing chunk number 0 for toast value 123456 in pg_toast_123456`
This happened before and I manually nulled out those values, but suddenly this week again a corruption. What should I check first?
