Hello,

We have :

travelexpressus=# select version();
                                                 version
------------------------------------------------------------------------

 PostgreSQL 7.4.2 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.3.2
20031022 (Red Hat Linux 3.3.2-1)
(1 row)

travelexpressus=# \x
Expanded display is on.
travelexpressus=# show STATS_START_COLLECTOR;
-[ RECORD 1 ]---------+---
stats_start_collector | on

travelexpressus=# show STATS_COMMAND_STRING;

stats_command_string | on

travelexpressus=# show STATS_BLOCK_LEVEL;

travelexpressus=# show STATS_ROW_LEVEL;

travelexpressus=# show STATS_RESET_ON_SERVER_START;

stats_reset_on_server_start | on

travelexpressus=# select * from pg_stat_activity;
