Postgres SQL Monitor tool

Is there a log file, or a method of logging all the SQL statements a
postgres server processes. I can look at pg_stat_activity which tells me
each postgres process and the current query running, however I wanted to see
a log file, similar to SQL Servers Profiler, where I can capture all the SQL
being run. I guess I could write some external process to poll the
pg_stat_activity and collect current processors and SQL commands being run.
