Thread: copy a postgres dbase to the same machine with different name?
Hi everyone,
For a project here at work I look after a web app that communicates with a postgresql database. We need to clone/copy the existing database to run app upgrades on the clone database and then use the upgraded database in place of the original.
I've read the pg_dump/pg_restore man pages, tried to google for a technique, but haven't found anything that adequate explains it & i'd rather not screw up a live database <grin>
Thanks for any help,
Jon.

Are you talking about cloning the whole installation to run under a
separate postmaster? Or are you trying to create a new database with
a different name under the same postmaster?
If the latter, and you can idle the database while copying it, the
TEMPLATE option to CREATE DATABASE will serve.
