An unfair comparision....

I'm curious how PostgreSQL compares to Oracle in terms
of stability and speed.  My company is looking into
alternative database software for our product but we
need to know if it's stable enough for our needs.

  Our current requirements list for a good Database
software application are the following.

 1. Stability - It can survive power outages.
 2. Speed - We're only going to perform very basic
read and write transactions.  Some tables are rather
large but over all, we need a at least 200 sql
transactions per second.
 3. Redudency - Can we have two physical systems with
one database being updated by the master database
automaticly in case of failure.  This is above and
beyond RAID.
 4. Solaris Support - I'm already positive that
PostgreSQL can run on Solaris, but how well is it
supported?

  If someone can adaquitly answer those issues for me,
I would be extreamly greatfull.  Thank you.

   Tony
