The question is, what exactly do you want to optimize? The database configuration
or your own SQL-Querys?


I think, the default parameters (in postgresql.conf) are okay for the

(This is from the doc-bot in the IRC-Channel #postgresql)


If you ask how about query-tuning, then you should read more about
indexes, vacuum and explain analyze:
