Обсуждение: Postgresql Duplicate DB

Hi. Not sure if the fastest, but the first that comes up to my mind is using pg_dump and psql. First you create your new database, then you run this(replacing as needed):

pg_dump OLDDB | psql NEWDB

If it is in the same database cluster, you can use

   CREATE DATABASE newdb TEMPLATE olddb;

Make sure nobody is connected to "olddb" when you do that.

If you want to clone a whole database cluster, you can run

   pg_basebackup -D /new/cluster/directory --wal-method=stream

and recover the new cluster with "restore_command = 'true'".
