How to enable pragmas with SqliteDialect

Hello, I am using SqliteDialect and want to enable foreign_keys pragma. From SQLite Docs:

Foreign key constraints are disabled by default (for backwards compatibility), so must be enabled separately for each database connection.

sqlite> PRAGMA foreign_keys = ON;

sqlite> PRAGMA foreign_keys = ON;

I was trying to use SqliteDialect's onCreateConnection to enable this.

new SqliteDialect({ 
    database: new SQLite(getNbDBPath(id)),
    onCreateConnection: async (conn) => {
        conn.executeQuery(/* ... */)
    }
})

new SqliteDialect({ 
    database: new SQLite(getNbDBPath(id)),
    onCreateConnection: async (conn) => {
        conn.executeQuery(/* ... */)
    }
})

But the issue is that onCreateConnection provides me a DatabaseConnection instance. DatabaseConnection.executeQuery expects a CompiledQuery. To compile a query I can do something like

sql`PRAGMA foreign_keys = ON;`.compile(db)

sql`PRAGMA foreign_keys = ON;`.compile(db)

but the problem is that I don't have a db because I am creating a dialect which I will then use to create a db. Is there something I am missing or is there a better way to achieve this ?
