Moving postgresql data cluster

问题

Our postgres data folder was installed on a drive with very limited space. I'm now trying to move it over to a newly mounted drive (more space). I've followed several blog posts and they all say...

1. stop service
2. copy data cluster
3. update postgresql-9.1 file (PGDATA=)
4. restart service

The service starts but when I go to connect, it gives me "could not connect to server: Connection refused"

I tried telnet-ing to port 5432 and nothing.

Here is the link to what I've been trying: http://www-01.ibm.com/support/docview.wss?uid=swg21324272

Thanks everyone for your help. Looks like the problem was with permissioning.

Instead of doing

cp -R fromfolder tofolder

I did

cp -a fromfolder tofolder

And that solved it. Thanks all.
