Re: question

Thanks Adrian. I've got postgres 9.4 running on a second RHEL 6.5 machine.
This is the machine I want to restore the pg_dump to.

Last week, I ran this command on the main PG 9.4 db server:

./pg_dump -t RECORDER -Fc postgres -Z0 | xz -9 > /tmp/dump_xz

The -Z0 turns off compression. So I used xz and noticed the file was not
that big.

Now, I got PG 9.4 running today on a 2nd machine. I just did the initdb,
started service, updated the hba.conf and postgres.conf to accept
connections from the outside and then restarted service.

1) When i attempt to restore the archived, I get an error to provide
password and I am confused what to do here.

2) is it correct to do xzcat and then pipe that to pgsl? I want to restore
on mymachine.com

3) on the target machine, I ran initdb and by default it creates postgres.
Will that be a problem when restoring?

On this machine I am connected as root.

xzcat dump_xz |/opt/PostgreSQL/9.4/bin/psql -h mymachine.com postgres

Thank you!
