### PostgreSQL
When you use `:return-keys true` with `execute!` or `execute-one!` (or you use `insert!`), PostgreSQL returns the entire inserted row (unlike nearly every other database that just returns any generated keys!).
If you have a query where you want to select where a column is `IN` a sequence of values, you can use `col = ANY(?)` with a native array of the values instead of `IN (?,?,?,,,?)` and a sequence of values.
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.
