How to hack the storage component？
Hi folks,
Currently, I'm trying to read the storage component, since it's biased
towards the lower layer, seems more difficult to understand and debug. All
the materials I have found are the original papers on
http://db.cs.berkeley.edu, I'm wondering how much it have been changed
since Postgres. Could you please give me some suggestions? Thanks.
Regards.

It has changed a lot since the Berkeley times. I doubt the original
papers are of much use anymore in understanding modern PostgreSQL.
You'll want to read src/backend/storage/smgr/README, although there
isn't much there. Also make sure you read the "Database Physical
Storage" section in the user manual,
http://www.postgresql.org/docs/devel/static/storage.html.

Thank you very much.
Based on your information, I find an interesting page including your
comment:
http://code.metager.de/source/history/postgresql/src/backend/storage/smgr/README
.
Seems all guys are in the core team, really nice job.
Thanks again for your kind reply and "2 phase commit" contribution.
