- `TEXT` in Redshift is equivalent to `VARCHAR(256)`, use
  `VARCHAR(1024)` instead
- Unskip all tests skipped on Redshift due to sample dataset issue
- Add explicit `:order-by` to `join-source-queries-with-joins-test`
  to make it pass in Redshift as Redshift does not preserve order
  after join (like a lot of other distributed query engines)
- Add `VACUUM` and `ANALYZE` call after INSERT to improve performance
