SQL has three parts (at least):

- description of your data (create table basics. This is called Data Description Language or DDL in the standard)

- the queries that is the first thing people think of when they hear 'SQL'

- all kinds of extra info that controls efficiency, resilience, etc. ((partial) indices, choice of storage engine, whether to materialize views, how to grow database files, etc.).

That last part could easily include ways to specify automatic replication (but probably wouldn't be standardized soon)
