Problem with createdb

Hi,
    I am experiencing a strange problem with createdb. It gives following error message.

***********
bin # ./createdb -U dpgres -p 9999 -h 127.0.0.1 -q mydb
************

However, when I remove the -h option, it works smoothly.

************
bin # ./createdb -U dpgres -p 9999 mydb
CREATE DATABASE
************

The changes in postgresql.conf file are:

shared_buffers = 300MB
work_mem = 150MB

My system has 2 GB of RAM.

The parameters in /etc/system are as follows.

set msgsys:msginfo_msgmnb=65536
set msgsys:msginfo_msgtql=1024
set shmsys:shminfo_shmmax=0x15E00000
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=256
set shmsys:shminfo_shmseg=256
set semsys:seminfo_semmap=256
set semsys:seminfo_semmni=512
set semsys:seminfo_semmns=512
set semsys:seminfo_semmsl=32


Can anybody help me understand what the problem might be?


Regards,
