it would also be able to suggest columns/fields from your database, as well as picking up errors. for example, given this table:
create table profiles (
id serial primary key,
first_name text,
last_name text
);
and this query: select id, firstname from profiles;
it would then help to detect if you had an error in your select query (in this case, "firstname" should be "first_name"), and your code editor would show a warning, even before you try to run the code inside your database
