Обсуждение: Copy database
Hi all, I am looking for a way to copy whole database to another existing database. Any suggestions ? --------------------------------------------- Best regards, Krzysztof Szadkowski
pg_dump -h sourcehost -U sourceuser sourcedatabase | psql -h desthost -U
destuser destdatabase
you may have to add a parameter for the password depending on your pg_hba.conf
settings. Both databases need to be network enabled and have a pg_hba.conf
entry for the machine you're running this command on.

Sometimes you want to copy the whole DBMS to another machine where the same postgres version is running. You can just copy the ./data directory, check the permissions (chown -R postgres ./data) and run postmaster with this data directory (postmaster ... -d ./data).
Note: Like that, you can't copy a certain database. You have to use the same postgres version for that...

createdb --template=sourcedatabase newdatabase will also work (and probably work faster) if you can kick everyone out of sourcedatabase and you're doing all this on one machine.
