That would be the behavior of PQconnectdb(), not PQconnectStart().

Have you read that part of the doc:

<quote>
Other states might also occur during (and only during) an asynchronous
connection procedure. These indicate the current stage of the connection
procedure and might be useful to provide feedback to the user for example.
These statuses are:

CONNECTION_STARTED

Waiting for connection to be made.
CONNECTION_MADE

Connection OK; waiting to send.
CONNECTION_AWAITING_RESPONSE

Waiting for a response from the server.
CONNECTION_AUTH_OK

Received authentication; waiting for backend start-up to finish.
CONNECTION_SSL_STARTUP

Negotiating SSL encryption.
CONNECTION_SETENV

Negotiating environment-driven parameter settings.

Note that, although these constants will remain (in order to maintain
compatibility), an application should never rely upon these occurring in a
particular order, or at all, or on the status always being one of these
documented values. An application might do something like this:

switch(PQstatus(conn))
{
case CONNECTION_STARTED:
feedback = "Connecting...";
break;

case CONNECTION_MADE:
feedback = "Connected to server...";
break;
