Didn't the 08001 get returned after you failed to reconnect?  As follows, I got 08S01 when I killed backend while it
wasrunning an SQL statement (e.g. SELECT pg_sleep(1000)). 

[isql command of unixODBC]
$ isql -v postgres
...
SQL> select pg_sleep(1000);
[ISQL]ERROR: Could not SQLExecute
[08S01]server closed the connection unexpectedly
    This probably means the server terminated abnormally
    before or while processing the request.
;
The connection has been lost

[my test app using SQLExecDirect]
08S01: server closed the connection unexpectedly
    This probably means the server terminated abnormally
    before or while processing the request.
;
The connection has been lost
