 Only accretive/fixative changes will be made from now on.
 
 * 1.3.next in progress
+  * Address [#283](https://github.com/seancorfield/next-jdbc/issues/283) by adding a note in the documentation, linking to the PostgreSQL bug report about `ANY(array)`.
   * Address [#269](https://github.com/seancorfield/next-jdbc/issues/269) by adding `:name-fn` as an option (primarily for the SQL builder functions, but also for result set processing); the default is `clojure.core/name` but you can now use `next.jdbc.sql.builder/qualified-name` to preserve the qualifier.
   * Update testing deps.

 What does this mean for your use of `next.jdbc`? In `plan`, `execute!`, and `execute-one!`, you can use `col = ANY(?)` in the SQL string and a single primitive array parameter, such as `(int-array [1 2 3 4])`. That means that in `next.jdbc.sql`'s functions that take a where clause (`find-by-keys`, `update!`, and `delete!`) you can specify `["col = ANY(?)" (int-array data)]` for what would be a `col IN (?,?,?,,,?)` where clause for other databases and require multiple values.
