Re: Where should I start for learn development

Thanks to all for all the good advice. I was thinking myself to work in any
of the open source project and contribute there. As a database developer I
think Postgresql is one of the best places for me where I may enjoy working
and see the outcome.
If you ask about goal, I was thinking to work in a large project where the
great hacker may be working for parallel execution of a query. At present,
I need it badly. I know I may achieve a bit of that using pgpool load
balancer or grid sql. But it would be nice if we get it at core Postgresql.
Criag, you really tell a good point. At first I should start by writing
simple C functions as extension and then for more.
Thanks to all again.
