Before, the query would be formatted equivalent to the input string:
```
[2020-04-18T23:47:32Z DEBUG sqlx_core::postgres::executor] SELECT id, queue, ..., elapsed: 2.320µs
SELECT id, queue, payload, status, priority, created_at, updated_at
FROM jobs
WHERE status = $1
ORDER BY priority ASC, created_at ASC
```
After, the query is formatted cleanly and consistently:
```
[2020-04-19T00:30:18Z DEBUG sqlx_core::postgres::executor] SELECT id, queue, ..., elapsed: 2.280µs
SELECT
id,
queue,
payload,
status,
priority,
created_at,
updated_at
FROM
jobs
WHERE
status = $1
ORDER BY
priority ASC,
created_at ASC
```
This uses the `sqlformat` crate, which was ported from the
Javascript `sql-formatter-plus` library specifically for this purpose.
Prints each query performed at DEBUG level,
along with a timing of how long the query took
to execute.
Slow queries will be printed at WARN level.
Currently the slow query threshold is
hardcoded to 1 second.
