I have started using Postgresql database from today. In my limited DB knowledge itself, I was able make out the strength of this open source DB. Unlike MySQL, its tough to get clear cut documentation about Postgres from a single source. I have installed Postgres on my devel box running on Ubuntu 9.04 (64 bit edition) . Here is the logs from my console.
