Hello,

I am about to upgrade from 7.3.4 to 8.0.3, and I read that using a DB
replication tool is a good way to go about it.

I see there are multiple replicator choices:
  Slony-I
  Daffodil Replicator
  Mammoth Replicator

I was wondering if anyone has tried any 2 or 3 of them, and could share
the experiences.

My upgrade will be over WAN (old DB and new DB are in different hosting
facilities), and it's for a fairly small DB:

# du -sh ~postgres/data
4.6G    /var/lib/pgsql/data

Oh, and couldn't I just pg_dump my old DB, scp the file over to the new
DB host, and use psql -f dump-file-here ?  Seems simpler than messing
with replicators.

Thanks,
Otis
