If you do not have stats_command_string set to on in your postgresql.conf, you will see output similar to the following:

postgres=#  select * from pg_stat_activity;
 datid | datname  | procpid | usesysid |    usename    |        current_query         | query_start |         backend_start         | client_addr | client_port
