+## [1.23.0](https://github.com/sqlc-dev/sqlc/releases/tag/v1.23.0)
+Released 2023-10-24
+
+### Release notes
+
+#### Database-backed query analysis
+
+With a [database connection](config.md#database) configured, `sqlc generate`
+will gather metadata from that database to support its query analysis.
+Turning this on resolves a [large number of
+issues](https://github.com/sqlc-dev/sqlc/issues?q=is%3Aissue+label%3Aanalyzer)
+in the backlog related to type inference and more complex queries. The easiest
+way to try it out is with [managed databases](../howto/managed-databases.md).
+
+The database-backed analyzer currently supports PostgreSQL, with [MySQL](https://github.com/sqlc-dev/sqlc/issues/2902) and [SQLite](https://github.com/sqlc-dev/sqlc/issues/2903)
+support planned in the future.
+
+#### New `createdb` command
+
+When you have a cloud project configured, you can use the new `sqlc createdb`
+command to spin up a new ephemeral database with your schema and print its
+connection string to standard output. This is useful for integrating with other
+tools. Read more in the [managed
+databases](../howto/managed-databases.md#with-other-tools) documentation.
+
+#### Support for pgvector
+
+If you're using [pgvector](https://github.com/pgvector/pgvector), say goodbye to custom overrides! sqlc now generates code using [pgvector-go](https://github.com/pgvector/pgvector-go#pgx) as long as you're using `pgx`. The pgvector extension is also available in [managed databases](../howto/managed-databases.md).
+
+#### Go build tags
+
+With the new `emit_build_tags` configuration parameter you can set build tags
+for sqlc to add at the top of generated source files.
