 - **Change to the minimum number of replicas in a service**  
   Services which have been scaled up can now be [scaled back down](/manage/scaling) to use a single replica (previously the minimum was 2 replicas). Note: single replica services have reduced availability and are not recommended for production usage.
+- ClickHouse Cloud will begin to send notifications related to service scaling and service version upgrades, by default for administrator roles. Users can adjust their notification preferences in their notification settings.

+### Can I update primary key columns in PostgreSQL? {#can-i-update-primary-key-columns-in-postgresql}
+
+:::warning
+Primary key updates in PostgreSQL cannot be properly replayed in ClickHouse by default.
+
+This limitation exists because `ReplacingMergeTree` deduplication works based on the `ORDER BY` columns (which typically correspond to the primary key). When a primary key is updated in PostgreSQL, it appears as a new row with a different key in ClickHouse, rather than an update to the existing row. This can lead to both the old and new primary key values existing in your ClickHouse table.
+:::
+
+Note that updating primary key columns is not a common practice in PostgreSQL database design, as primary keys are intended to be immutable identifiers. Most applications avoid primary key updates by design, making this limitation rarely encountered in typical use cases.
+
+There is an experimental setting available that can enable primary key update handling, but it comes with significant performance implications and is not recommended for production use without careful consideration.
+
+If your use case requires updating primary key columns in PostgreSQL and having those changes properly reflected in ClickHouse, please reach out to our support team at [db-integrations-support@clickhouse.com](mailto:db-integrations-support@clickhouse.com) to discuss your specific requirements and potential solutions.
