Hi All, I try to query on pg_stat_activity but the returned result is only like this: teramedv2=> select * from pg_stat_activity where datname='teramedv2'; datid | datname | procpid | usesysid | usename | current_query | query_start -------+-----------+---------+----------+---------+---------------+------------- 17178 | teramedv2 | 32727 | 103 | test | | 17178 | teramedv2 | 26848 | 103 | test | | 17178 | teramedv2 | 563 | 103 | test | | 17178 | teramedv2 | 26799 | 103 | test | | (4 rows) the field current_query and query_start seems to me always null ... I try to do a long run select query on the other console and see the returned result from pg_stat_activity but the returned result is only new row with datid,datname,procpid,usename fields is filled with the correct value but current_query and query_start fields is always null. Is this an expected result ?
