Hello! Yesterday was everything OK. Today I got this message:

"The following error occured when trying to open the database: Failed to establish a connection to I27.0.0.1"

I made no changes at the computer and i donīt imagine what is the problem.

I went to PGAdmin but i could not acess the database and got this message:
"Server doesn't listen
The server doesn't accept connections: the connection library reports
could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432?
If you encounter this message, please check if the server you're trying to contact is actually running PostgreSQL on the given port. Test if you have network connectivity from your client to the server host using ping or equivalent tools. Is your network / VPN / SSH tunnel / firewall configured correctly?
For security reasons, PostgreSQL does not listen on all available IP addresses on the server machine initially. In order to access the server over the network, you need to enable listening on the address first.
For PostgreSQL servers starting with version 8.0, this is controlled using the "listen_addresses" parameter in the postgresql.conf file. Here, you can enter a list of IP addresses the server should listen on, or simply use '*' to listen on all available IP addresses. For earlier servers (Version 7.3 or 7.4), you'll need to set the "tcpip_socket" parameter to 'true'.
You can use the postgresql.conf editor that is built into pgAdmin III to edit the postgresql.conf configuration file. After changing this file, you need to restart the server process to make the setting effective.
If you double-checked your configuration but still get this error message, it's still unlikely that you encounter a fatal PostgreSQL misbehaviour. You probably have some low level network connectivity problems (e.g. firewall configuration). Please check this thoroughly before reporting a bug to the PostgreSQL community. "

Can you help me?

This is usually a firewall or windows update issue.

First try to reboot.

If no help, try this:

Start > Programs > PostgreSQL > 8.x > Stop Service

Start > Programs > PostgreSQL > 8.x > Start Service

If that doesnt help delete the \postgresql\8.x\data\postmaster.pid file, if you see it. And reboot.


If that doesn't help you will have to reinstall PostgreSQL completely

Thank you for the help.

For others information, the solution was this one:


delete the \postgresql\8.x\data\postmaster.pid file and reboot.

After this everything was back to normal! :)
