I have seriously updated the backend flowchart. In fact, the name is
gone, and it is now called "How PostgreSQL Processes a Query".
I have added several paragraphs describing the flow of data from one
module to another, and have added a section describing 'exactly' what is
stored in shared memory, and how it is used.
If you have current source tree, point your browser at:
file:/usr/local/pgsql/src/tools/backend
or the proper directory for your system. You can also view it on our
www site from the docs page.
I am interested in comments, suggestions, and any possible errors.
This will certainly help people get started coding, because at least
they will understand how all the parts fit together.
