All do what it looks like they do. > Since the file got uncompressed, I am now running the command: > psql -f /home/tsakai/Notes/postgres/dumpall20100822.0 > and I think it is working.

No. It's just telling you that from a performance perspective things would be faster with more checkpoint segments. Unless you spend a fair portion of your day restoring dbs, it's probably not big deal. If your machines only do a little writing at a time then you can probably leave it. However, increasing checkpoint segments does help a lot if you do handle a fair bit of writes, and it's cheap and easy to do. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
