I know we can know the currenct activity via pg_stat_activity. What's else
you guys use to debug.

Performance is a complex enough issue to warrant its own mailing list
(CPU type, number of cores, OS, OS settings, PG configuration, disk
type/count/filesystem/raid-configuration and so on).

Greg Smith's "PostgreSQL 9.0 High Performance" is worth every penny.

While waiting for it to arrive, peruse the pages at
http://wiki.postgresql.org/wiki/Performance_Optimization

Cheers,

Hi Steve,

This is a very good website. We use the postgresql 8.2. there may be a little different. It's very useful to me.

Thanks.
Regards.
