Re: invalid data in PID file

Actually i've been trying to setup my postgres database in a new machine.
the machine that i'm using right now is goin to die very soon. So i was trying to restore it in another machine but before that I have to install postgres in this new machine.

I installed postgres successfully, created a DB cluster using initdb comand after creating a user account that would use postgres and made it the owned of the location where DB was initialized.

Then I started my postgres service using
pg_ctl start -D /usr/local/pgsql/jsbali

That was the very first time i started it and it did not give me any errors.
After that I created a new DB server using PGAdmin3 and the server was created successfully.
When i tried connecting to this server, i gave me an error Ident Authentication failed and wanted me to do appropriate changes in pg_hba.conf file
However, in pg_hba.conf file, i have the settings for the trusted connection.
pg_hba.conf and postgresql.conf files i copied from my old Db server and overwrote on the ones that were created as a result of initidb in the new database.

Right after this point, pg_ctl start, stop and reload doesn't work at all.

There was some problem with postmaster.pid file, so i just removed it.

The last error that i got after tryin to start postgres is :

could not bind IPv6 socket: Address already in use.
HINT: Is another postmaster already running on port 5432? If not , wait a few seconds and retry.
LOG: could not bind IPv$ socket: Address already in use
