+>
+> The `paradedb/pg_analytics` extension has been discontinued and is archived. This decision was made because ParadeDB's work on Postgres analytics is now being done in our primary extension, `pg_search`. If you are looking for fast analytics on Postgres, we recommend you check out our [`paradedb/paradedb`](https://github.com/paradedb/paradedb) repository.
