Latest postgres stable version

Hi Team,

I am using Solaris-9 and pgsql-7.4.2. I am going to upgrade my DB to the
latest and stable release.

1. May I know what is the stable pgsql release and latest?
2. I heard the version 8.2.5 is stable, but when I searched for the
same on site, it has only 8.2.6. May I know which is stable.
3. Pls provide the link for the same.
4. Are there any changes required while installing or configuration
of pgsql when the DB has to be run on the SUN clusters.(Not DB
clustering.) I had 2 sun clusters running on the DB server with common
database. When I stop the DB on one cluster it is the DB is shut down,
but due to clustering, the DB is not getting stopped complete. Can any
one please suggest how to stop the DB server running on the clusters and
upgrade the latest pgsql.

Pls advice to guide me on this.

Regards,

G. V. Suresh Gupta
