Here’s my list of pointers:
- Power PostgreSQL – really detailed and up-to-date information on setting PostgreSQL runtime parameters. Don’t forget to check the annotated postgresql.conf with comments. BTW: Looking forward to reading the forthcoming book.
- Collection of PostgreSQL performance tips – a shopping lists of tips (both configuration as well as application design). The posts is a bit old, but many things (ecpesially the more general ones are still very relevant).
- Performance Tuning PostgreSQL – a decent link, explaining both runtime settings (some of this might be obsolete) and the general concepts:
EXPLAIN,ANALYZE, indices. - Postgres 8.x docs – explains runtime parameters in some detail.
