That's a meaningless number when you haven't specified what kind of iron
you intend to run on, nor how many reads and writes make up each
transaction. But AFAIK Postgres is reasonably competitive with Oracle
speed-wise. If you can get that speed with Oracle you can probably
manage it with Postgres too.

We are pretty weak in this area. There is a good overview of the state
of play at http://www.greatbridge.org/genpage?replication_top with links
to available solutions (all kluges to some extent, IMHO, but people are
using them) as well as work on better answers. I'd guess a good
integrated replication solution will be available sometime next year.

It works. <commercial>The two platforms that Great Bridge currently
offers commercial support contracts for are Linux and Solaris, so I'd
say it's supported well enough...</commercial>
