I wrote a small util called "pgtop" that does a top style listing on
PG in terms of cpu. I also have one called pgiomonitor (that is on
pgfoundry and mostly done) that does the same but shows you which
tables are producing the most IO)
http://postgresql.jefftrout.com/pgtop.pl
it only runs on linux and it must run on the same box as pg itself.
You may want to look at it and see if you can get anything good out
of it.
queries / second is tricky. You could look at my pgspy utility but
it is in C. It can give you queries / second data
