Hello!
Are there some presentations or documents of the internals of PostgreSQL
available?
Especially I'm looking for the concepts and detailed internals of general
transaction handling, internals of commit log, transaction logs,
pg_multixact, pg_subtrans, pg_tblspc and pg_twophase.
Also some comments about concurrent access with multiple processes,
locking and shared memory concepts (or other communication systems used)
would be nice.
I already found
http://www.postgresql.org/files/developer/internalpics.pdf
but some comments are missing to understand it well.
Thanx.
Ciao,
Gerhard
