+If you're using Spring Data JDBC with xref:packaging/aot.adoc[ahead-of-time processing] (targeting either the JVM or a native image), some additional configuration is recommended.
 To prevent the need for a DB connection during AOT processing, define a `JdbcDialect` bean that's appropriate for your application's database.
 For example, if you're using Postgres, define a `JdbcPostgresDialect` bean.
