track row / field usage

guys,
i want to track just how many times a particular row, field or
contained value gets queried / fetched? i guess a trigger like so
would do the trick:
on query, update value in column
even a log and then parsing it would help. but is there a cooler way-
some built-in stats counter? just trying to see which rows, fields or
values are most sort after.
cheers, jzs

Set the log_statement line in postgresql.conf to "all".
