Too many rows to serialize on postgres

I think the initialization is struggling with the amount of data in my database and it's timing out. Can you add an option to not serialize?

Error:
```
received: {"action":"exec","sql":"SELECT table_schema, table_name, column_name\n FROM information_schema.columns \n WHERE table_schema not in ('pg_catalog', 'information_schema', 'pg_internal')","id":3}
Error: Too many result rows to serialize: Try using a LIMIT statement.
```
