I would start by reading this web page:
http://powerpostgresql.com/PerfList
There are probably some other web pages out there with similar information,
or you can check the mailing list archives for a lot of info. If those
places don't help, then you should try to indentify what queries are slow,
post an EXPLAIN ANALYZE of the slow queries along with the relvent schema
info (i.e. table definitions and indexes).
