database creation failed

I'm new to cygwin(1.1.6) & postgreSQL(7.0.3).

when start postmaster:
postmaster -i&

I got:
DEBUG:  Data Base System is starting up at Thu Feb  8 10:12:53 2001
DEBUG:  Data Base System was interrupted being in production at Wed Feb  7
23:02:36 2001
DEBUG:  Data Base System is in production state at Thu Feb  8 10:12:53 2001

psql -h localhost template1

when try to create database
$ createdb test
psql: connectDBStart() -- connect() failed: No such file or directory
        Is the postmaster running at 'localhost'
        and accepting connections on Unix socket '5432'?
createdb: database creation failed

This is what I have in pg_hda.conf
# By default, allow anything over UNIX domain sockets and localhost.
local        all                                           trust
host         all         127.0.0.1     255.255.255.255     trust

Please help

Thank you
