Review comment (bug):
If possible, I would avoid the `?` here. Why? Because it's an internal code, and by adding `?` we might miss code paths that might require `true` instead. This is usually a pattern I follow inside code that isn't exposed to the user: the compiler fails all the instances of the code, and forces me to update them all. Would you mind doing that here and in the other function? 

Code after:
 * @returns The module import string for the DB client.
 */
function getDBModule(localExecution: boolean) {
	return localExecution
		? `import { createClient } from '${DB_CLIENTS.node}';`
		: `import { createClient } from '${VIRTUAL_CLIENT_MODULE_ID}';`;
}

export function getLocalVirtualModContents({
	tables,
	root,
	localExecution,
}: {
	tables: DBTables;
	root: URL;
	/**
	 * Used for the execute command to import the client directly.
	 * In other cases, we use the runtime only vite virtual module.
	 *

	localExecution: boolean;

	// If this is for the execute command, we need to import the client directly instead of using the runtime only virtual module.
