@ -15,6 +15,8 @@ Let's highlight some of these new exciting new capabilities in 21.10:
* Instead of logging every query (which can be a lot of logs!), you can now log a random sample of your queries. The number of queries logged is determined by defining a specified probability between 0.0 (no queries logged) and 1.0 (all queries logged) using the new `log_queries_probability` setting.
* Positional arguments are now available in your GROUP BY, ORDER BY and LIMIT BY clauses. For example, `SELECT foo, bar, baz FROM my_table ORDER BY 2,3` orders the results by whatever the bar and baz columns (no need to specify column names twice!)
