I am getting this error with Postgresql 8.4 on Ubuntu Hardy:
$./postgres -D /usr/local/pgsql/data LOG: could not bind IPv4 socket: Cannot assign requested address HINT: Is another postmaster already running on port 5432? If not, wait a few seconds and retry. WARNING: could not create listen socket for "localhost" FATAL: could not create any TCP/IP sockets
Here is my hosts file content (been finding a lot of stuff about this so just posting it now:
127.0.0.1 localhost 127.0.1.1 Home-Dev
Update: $ sudo netstat -tap | grep 5432 Came up blank.
I should also mention this is installed from source (I had original tried to install from the package and was getting the same error).
