Nesta página, você verá como criar um banco de dados PostgreSQL no AlloyDB para PostgreSQL. Antes de criar um banco de dados, é necessário criar um cluster e a instância principal dele.
Para criar um banco de dados em um cluster do AlloyDB, conecte um cliente psql à instância principal do cluster e execute um comando CREATE
DATABASE do PostgreSQL.

Before you can create a database, you must [create a\ncluster and its primary instance](/alloydb/docs/cluster-create).\n\nTo create a database in an AlloyDB cluster, you connect a `psql`\nclient to the cluster's primary instance and then run a PostgreSQL `CREATE\nDATABASE` command.\n\n\nBefore you begin\n----------------\n\n- The Google Cloud project you are using must have been [enabled to access AlloyDB](/alloydb/docs/project-enable-access).\n- You must have one of these IAM roles in the Google Cloud project you are using:\n - `roles/alloydb.admin` (the AlloyDB Admin predefined IAM role)\n - `roles/owner` (the Owner basic IAM role)\n - `roles/editor` (the Editor basic IAM role)\n\n If you don't have any of these roles, contact your Organization Administrator to request\n access.\n\n\u003cbr /\u003e\n\nProcedure\n---------\n\n1. Connect a `psql` client to the cluster's primary instance, as described in [Connect a psql client to an\n instance](/alloydb/docs/connect-psql).\n2. At the `psql` command prompt, enter a `CREATE\n DATABASE` command, as described in the [PostgreSQL\n documentation](https://www.postgresql.org/docs/16/sql-createdatabase.html). For example: \n\n ```sql\n CREATE DATABASE DATABASE_NAME;\n ```\n\n Follow the PostgreSQL rules in\n [Identifiers\n and Key Words](https://www.postgresql.org/docs/16/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS) when you create your database name."]]
