Dump and Restore

One way is to create another instance of your PG server,
using a different PGDATA path.
So your actual data won't be overwriten.

Are you using pg_dump or pg_dumpall? I just use pg_dump on individual
databases (pg_dumpall works on the whole cluster) and can restore that to
any database.

Assuming you're using Unix Box
1. Dump your database DB_X
pg_dump -v -U postgresUsername DB_X | gzip -f - > DB_X.gz

2.Create database DB_Y
psql -U postgresUsername template1
CREATE DATABASE DB_Y
\q

3. zcat DB_X.gz | psql -U postgresUsername -f - DB_Y

OK here's a recipe:
If you're using pg_dump as in:
pg_dump dbName > fileName
create your new database:
createdb myNewDB (don't forget your encoding)
and then restore from the dump:
psql -d myNewDB -f fileName

Ron

I am using pg_dump.

It means that I can't restore to a different name
database??

If you use pg_dump[all] without other options it will dump to a text
file. Just edit the database name.
