New to PostgreSQL Question (Query Optimizer)
Rick Windham <rick@chapwin.com> — 1998-02-19T21:35:16Z
Hello, I'm newly into PostgreSQL from a SYBASE world and I haven't had a lot of time to get into the code, so bare with me please. Is there a query optimizer in PostgreSQL? or if not are there plans for one? And are there plans for anything like clustered indexes? I'm curious because one of the jobs I almost took a few years ago was working on the query optimizer itself. And please forgive me current ignorance of the architecture of your engine.

If you look in the current sources, the optimizer directory has a README that describes some of it. You will need the 6.3/snapshot release from ftp.postgresql.org to see the README, or go to www.postgresql.org, and go to support/documentation, and choose the nice program flowchart. You can cruise around in there, and see the source and README's. -- Bruce Momjian maillist@candle.pha.pa.us
