Hello to everyone,
I have a application using Postgres DB and I going to create a new version
on the same server... I would like duplicate my database with all structure
and data
like that, I can update this new version and keep the last one active
during the release version.
BUT, doesm't work =(
First I create the backup, like that :
pg_dump > db.out
After I try to duplicate this one :
So I create a other user "new-user" and I create a new db "new-db" (new-user
is the owner new-db)
next step :
change 1 ligne on db.out file :
Replace : "\connect - dbname" by "\connect - new-db"
To finish, I try that :
psql new-db< db.out
Of course, it doesn't work, otherwise I won't disturb you =)
Error message:
1: You are now connected as new user new-db
2: ERROR: Relation 'table1' already exists
3: ERROR: Relation 'table1' already exists
4: ...
I tried a lot of think without success, Some helpsssssssss pleaseee.
