node-postgres - Is done() required if node-postgres .connect() returns with an error?

Question

From the docs it sounds like err is not null if there was a problem getting a client from the pool. If that's the case, does it mean done() doesn't need to be called?

pg.connect(connString, function(err, client, done){
    if (err) { done(); return err; }

    ...
});

or

pg.connect(connString, function(err, client, done){
    if (err) { return err; }

    ...
});

Answer 1

您仅在成功done()时调用，即is或。connect()errnullundefined

所以第二个例子是正确的。
