n8n errors / Schema

There was an error initializing DB: relation "credentials_entity" does not exist

platform: n8n / category: Schema

Cause

n8n's Postgres migrations run against the wrong schema when DB_POSTGRESDB_SCHEMA is set to anything other than 'public', leaving tables uncreated.

Fix

Set DB_POSTGRESDB_SCHEMA=public or remove the variable so n8n uses the default. If you need schema isolation, create it first and grant the user full privileges before starting n8n. After fixing, wipe the database and let n8n re-run migrations cleanly.
