The log_truncate_on_rotation parameter is set to on.

There are a couple of ways. Assuming that it's the same database, and it's up

Assuming:

insert into bar (select * from foo);
would stick everything from foo.col1 and foo.col2 into bar.col2

Reading this thread confuses me a little bit. There is no need to backup

- it's really easy. This is how we copy from production to testing and development and how we do nightly backups.

Hi,
I'm currently restoring a fairly large DB from a pg_dump and it's taking
about 12 hours to finish. The main part of this time is spent creating
indexes. Is there anyway I can speed up the restore process, or do i just
have to wait? I'm using postgres 8.1.3 on freebsd and the pg_dump is

There's not much you can
Title: RE: [ADMIN] Restore of pg_dump taking a long time...
I have found that the following steps have increased the speed of my restores:
1. dropdb DBNAME
2. createdb DBANME
3. Increase maintenance_work_mem as Tom mentioned. I do this at restore/runtime
4. Increase work_mem as Tom mentioned

I would typically drop the indicies before taking the dump, and recreate
in the new instance. I know the loads go alot faster that way. Perhaps
the index creation would be the same.
