Re: Database port changing issue

["Chris Hoover" <revoohc@xxxxxxxxx>]

sounds like you might have a firewall blocking the new port.  Make sure you can connect locally the the database, and then get a hole poked in your iptables firewall (assuming this is a linux server)

HTH,

Hi to all,

 

I am facing an issue while changing database port in the new version 8.1. The previous version which i used was 7.3 and for the port change i used to change in postgresql.conf

 

From PG 7.3
#---------------------------------------------------------------------------
# CONNECTIONS AND AUTHENTICATION
#---------------------------------------------------------------------------

# - Connection Settings -

#tcpip_socket = false
#max_connections = 100
 # note: increasing max_connections costs about 500 bytes of shared
 # memory per connection slot, in addition to costs from shared_buffers
        # and max_locks_per_transaction.
#superuser_reserved_connections = 2
port = 5432
#unix_socket_directory = ''
#unix_socket_group = ''
#unix_socket_permissions = 0777 # octal
#virtual_host = ''  # what interface to listen on; defaults to any
#rendezvous_name = ''  # defaults to the computer name

# - Security & Authentication -

#authentication_timeout = 60 # 1-600, in seconds
#ssl = false
#password_encryption = true
#krb_server_keyfile = ''
#db_user_namespace = false

 

 

Now for the port change in the newer version i tried to change the same as shown below in postgresql.conf.

 

From PG 8.1

#---------------------------------------------------------------------------
# CONNECTIONS AND AUTHENTICATION
#---------------------------------------------------------------------------

# - Connection Settings -

listen_addresses = 'localhost'  # what IP address(es) to listen on;
     # comma-separated list of addresses;
     # defaults to 'localhost', '*' = all
port = 5478
max_connections = 100
# note: increasing max_connections costs ~400 bytes of shared memory per
# connection slot, plus lock space (see max_locks_per_transaction).  You
# might also need to raise shared_buffers to support more connections.
#superuser_reserved_connections = 2
#unix_socket_directory = ''
#unix_socket_group = ''
#unix_socket_permissions = 0777  # octal
#bonjour_name = ''   # defaults to the computer name

# - Security & Authentication -

#authentication_timeout = 60  # 1-600, in seconds
#ssl = off
#password_encryption = on
#db_user_namespace = off

# Kerberos
#krb_server_keyfile = ''
#krb_srvname = 'postgres'
#krb_server_hostname = ''  # empty string matches any keytab entry
#krb_caseins_users = off

# - TCP Keepalives -
# see 'man 7 tcp' for details

#tcp_keepalives_idle = 0  # TCP_KEEPIDLE, in seconds;
     # 0 selects the system default
#tcp_keepalives_interval = 0  # TCP_KEEPINTVL, in seconds;
     # 0 selects the system default
#tcp_keepalives_count = 0  # TCP_KEEPCNT;
     # 0 selects the system default

 

But i am getting an error as mentioned below

 

org.postgresql.util.PSQLException: Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.

 

What are the changes that i have to do for changing port.

 

If i am replacing it to 5432, it is working fine.

 

I had a great support and help from this mailing team and i expect the same.

 

Thanks to all in advance.

 

Regards

 

Mohamed Fazil
