Google Data Cloud update: BigQuery adds column aliases, cross-region table copy GA

[Google Cloud] Google Cloud detailed data cloud updates for October 19-23. According to Google Cloud, GoogleSQL in BigQuery now supports column aliases in SELECT and WHERE clauses (GA opt-in), reducing nested subqueries and simplifying migrations from Snowflake and Teradata, while cross-region table copying is now generally available to streamline regional data replication and disaster recovery. Conversational analytics in BigQuery expanded to Montréal and Toronto and now supports exporting agent responses to CSV or PDF. AlloyDB Omni 18.4.0 is GA with PostgreSQL 18.4, a query insights extension and Thales CipherTrust Manager support for transparent data encryption. Cloud SQL for PostgreSQL added managed connection pooling and now defaults to Private Service Connect for new instances in new projects. Google Cloud said digital identity platform Unico, after moving to BigQuery and Spanner, has prevented over $5 billion in fraud.
