To quickly find out a subset of slow queries on your production system, you
can use the pgfouine tool:
http://pgfouine.projects.postgresql.org/
If you then want to make some measurements of PostgreSQL performances with
some different settings and compare them, consider using the tsung tool (and
may be tsung-ploter companion tool to graph several benchs onto the same
charts for comparing purpose):
http://pgfouine.projects.postgresql.org/tsung.htmlhttp://tsung.erlang-projects.org/http://debian.dalibo.org/unstable/
This latter link also contains a .tar.gz archive of tsung-ploter in case
you're not running a debian system. Dependencies are python and matplotlib.
