Обсуждение: Moving data directory
Hi All, I'm very new to postgresql and would like to move my data directory to another partition in Ubuntu. The standard installation is in /usr/lib/postgresql. How do I move it into /var/lib/postgresql. Regards, Dino -- To Analyze Is To Know Batte Field, Differ from Battle Itself
You can do an initdb -d /var/lib/postgresql to initialize the data directory in
the /var/lib/postgresql directory. If you also have data in the
/usr/lib/postgresql - make sure you back it up and restore it in the new
directory.

Hi Srinivas, Is it permanently change it ? Do I have to change some entry in configuration file ?

How do I move it into /var/lib/postgresql. The standard data directory on Ubuntu *is* /var/lib/postgresql. You must be confusing something. -- Peter Eisentraut http://developer.postgresql.org/~petere/
No this will permanently change it.

I don't think there is anything internal to pg that locks the data
location. Just tell postmaster where you move it to. Shut down the
postmaster and move it and start it with the -D flag pointing to the
new location:
$ pg_ctl start -D /var/pgsql/data

Hi Ray, Sorry for late reply. Yes, I have tested your instructions and working well. The think is now I need to configure so that it will always automically start with the new location. Thank you very much for the detailed instructions, really appreciated it.

Each time you start postgres server using pg_ctl you have to mention the data directory location using -D option. Alternatively you can specify in the data_directory parameter of postgresql.conf file. - vishal >From: "Linux Geeks" <indolinux.geeks@gmail.com> >To: "Ray Stell" <stellr@cns.vt.edu> >CC: pgsql-admin@postgresql.org >Subject: Re: [ADMIN] Moving data directory >Date: Tue, 22 May 2007 10:45:17 +0700 > >Hi Ray, > >Sorry for late reply.

No needs to specify in pg_ctl start/stop clause instead add a variable in PATH. PG_DATA = d:\postgresdata\data. It is start by just typing pg_ctl start/stop.

This is also an alternative that can be used.
