Handle multi-statement queries

We need to be able to handle queries like this:

const query = `
    CREATE TABLE ids(id integer); 
    INSERT INTO ids(id) values(1); 
    INSERT INTO ids(id) values(2);
`;

await client.query(query);

I’m not sure how to nicely handle results, currently QueryResult has rows property that stores data returned from query. One idea is to subclass QueryResult and create MultiQueryResult that has slight different API and leave it up to user to handle that properly.

Comments welcome

That’s a separate issue, I just want to prevent using multi-statement queries in query because I don’t want to give it QueryResult | QueryResult[] return type. 95% of queries will be single queries and there’s really no need for devs to check every time if they got array or single result.
