Dear Sir,

I am extremely sorry i was just going to apologize for the mistake.

But i like the way pg_dump behaves , it refuses to work unless
-i is specified. Actually my colleagues complained that \d is not
working.

I think they got the database prompt as they get everyday and
did not notice the warning. ( even i missed to see the WARNING)

Warm Regds
