I would like to find the current (and very recent) SQL statements. I went through 'pg_stat_activity'. But it showed only the current statement I was issuing. Going through the defintion of 'pg_stat_activity' I came across pg_stat_get_backend_activity(), and I thought if I could get the source of this function I would be able to further. But I can't see the definition of this function.
Am I on the right direction, or is there an easier way? I would appreciate if someone can give some suggestions.
