I fear that the patch 'Additional chapter for Tutorial' grows beyond
manageable limits. It runs since nearly one year, the size of 228 KB is
very huge, many people havemade significant contributions. But a commit
seems to be in far distance. Having said that, I'm pleased with Heikki's
proposal to split changes in the existing file 'arch-dev.sgml' from the
rest of the patch and commit them separately.

But I have some concerns with the chapter '51.2. How Connections Are
Established'. It uses central terms like 'client process', 'server
process','supervisor process', 'master process', 'server tasks',
'backend (server)', 'frontend (client)', 'server', 'client'. Some month
ago, we have cleared his terminology in the new chapter 'glossary'. As
long as it leads to readable text, we shall use the glossary-terms
instead of the current ones. And we shall include some links to the
glossary.

I propose to start a new thread which contains only changes to
'arch-dev.sgml'. In pgsql-hackers or in pgsql-docs list? Initialized by
Heikki or by me?
