Error connecting to remote socket

Hi,

I am new to PosGreSql and have problem connecting to PostGreSql from a
machine with pslodbc driver. I don't know what is wrong but in my
simple code to connect to the database using ODBCConnection from the
server machine, it does not send out error message when I specify the
server as 'localhost' but when I set the server as 'Dbsvr' in the
connection string then it sent out ODBC error that it could not connect

to data source, could not connect ot remote socket. I would appreciate
if anyone can enlighten me. My postgresql.conf is below:

"

#-----------------------------­------------------------------­----------------

# FILE LOCATIONS
#-----------------------------­------------------------------­----------------

# The default values of these variables are driven from the -D command
line
# switch or PGDATA environment variable, represented here as ConfigDir.

# data_directory = 'ConfigDir' # use data in another directory

# hba_file = 'ConfigDir/pg_hba.conf' # the host-based authentication

file
# ident_file = 'ConfigDir/pg_ident.conf' # the IDENT configuration
file

# If external_pid_file is not explicitly set, no extra pid file is
written.
# external_pid_file = '(none)' # write an extra pid file

max_connections = 100

shared
# memory per connection slot, in addition to costs from

# and max_locks_per_transaction.

Thank you in advance,
