Hi Guys,

We are new to PostgresSQL and in the process of learning.

Could you please point us to a simple white paper/doc which describes the
Conceptual Architecture of PostgresSQL?

I don't know what you mean by "Conceptual Architecture."

Can you clarify?

Best Wishes,
Chris Travers

Ahh, odd question. Have you read the fine online manual?

http://www.postgresql.org/docs/9.1/interactive/index.html

Read about Relational Theory, and MVCC (ask google).

Have you read Greg's book?

After that, read the source code.
