Обсуждение: moving postgres data
Hi all I have data in a postgres database on one server and have to move it to a new server that has been set up with a new version of postgres. The database is an exact copy. what is the best way of moving the thing across? do i set up the tables on the new box and write scripts to move it across or is there another way of doing this? I don't have root access on the new server but can probably talk the sys admin into a little work if i have to. ta

Easiest way would be to dump the database to a text file: % pg_dump yourdatabase > /path/to/dumpfile copy it to the new server, and read it to an empty database using psql -e: % psql -e yourdatabase < /newpath/to/dumpfile This way all the schema are recreated, and the data loaded into them, automatically -- you don't have to set anything up by hand. See the documentation on pg_dump for more information. best, Mo Mo Holkar Digital Mind Games -- log on to take over mo.holkar@digitalmindgames.com http://www.digitalmindgames.com
