I don't know if there are tools or settings available for PostgreSQL that do such number-of-query-accounting; but you can set the log_min_duration_statement value to 0 to log all statements with their duration. See http://www.postgresql.org/docs/8.1/interactive/runtime-config.html for more options on runtime configuration, especially 17.7 and 17.8 might be of interest for you.
