 | `node.psql(query, ...)` | Runs query via `psql` command and returns tuple `(error code, stdout, stderr)`. |

 | `node.execute(query, ...)` | Connects to PostgreSQL using `psycopg2` or `pg8000` (depends on which one is installed in your system) and returns two-dimensional array with data. |
 | `node.connect(dbname, ...)` | Returns connection wrapper (`NodeConnection`) capable of running several queries within a single transaction. |
