the postgresql client is running under win98 and the server under FreeBSD3.1
when I'm trying to connect to the server and the server is not running, the
error message is:
connectDB() -- socket() failed:
errno=0
No error
and when the password is incorrect, i have the same error
it is no way to difference the errors !!!
