Measuring Lock Performance

От

Does anybody know if it is possible to use the statistics collected by
PostgreSQL to do the following, and how?

- view all locks held by a particular PostgreSQL session (including how to
determine
  the session ID#)

- determine effect of lock contention on overall database performance, as
well as the
  extent to which contention varies with overall database traffic

I am using version 8.0.2 on Windows 2003.
