[HACKERS] 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. Chaoyong Wang

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. - Heikki -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

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. Regards.
