+In .NET Aspire 9.3, the `WithCreationScript()` method is supported for the PostgreSQL integration but, because there is no `USE DATABASE` in PostgreSQL, it only supports operations against the default database. For example, you can issue `CREATE DATABASE` statements to create other databases, but you can't populate them with tables and data. Instead, you must use a bind mount and deploy the setup SQL script to it, so that the data is seeded when the container initializes the database.
