Simple ruby program that shows you queries running using pg_stat_statements.
This is different from the pg_stat_activity view in that it shows you all the queries that have run since the program was started, not just the queries running at the moment when you're looking at it.
gem install pg_qtop
pg_qtop -d DATABASE -h HOSTNAME -p PORT -U USER
In order to filter queries on a certain table, specify it with -t:
pg_qtop -d DATABASE -t TABLE
You can also filter the kind of statements that are shown with -s, e.g.:
pg_qtop -d DATABASE -t TABLE -s insert
AVG | CALLS | HIT RATE | QUERY

The view auto-refreshes every second.
