feat: add CRUD APIs on Databases

Google APIs · copybara-github · commit 48c3f2f1639c · 2025-09-26T10:42:20.000-07:00
feat: add PG 17 as a Database version
chore: annotate `EncryptionConfig.kms_key_name`, `SecondaryConfig.primary_cluster_name`, `PrimaryConfig.secondary_cluster_names`, and `PscInstanceConfig.service_attachment_link` with what resource they're referencing
feat: add configuration for Managed Connection Pool
feat: update `Database.charset` to be immutable
feat: add additional fields to Database object to specify the collation type, character type, if it is a template database, and the template to use for the database
feat: add field to ExecuteSQL request to just validate the sql statement
feat: add fields on the estimated/actual start/end times for an Upgrade Cluster operation
docs: specify that the STOPPED state is not used for clusters anymore
fix!: An existing enum `PoolMode` is removed from the `ConnectionPoolConfig`
