my GUC is configured like this:

#
#       Access statistics collection
#
stats_start_collector = true
stats_reset_on_server_start = true
stats_command_string = true
stats_row_level = true
#stats_block_level = false

how come there is not a single row in pg_statio_user_tables
any of the stat is having a non zero value ?

tradein_clients=#  SELECT schemaname,relname,heap_blks_read,heap_blks_hit
from  pg_statio_user_tables where ( heap_blks_read > 0 or heap_blks_hit >0 or
idx_blks_read >0 or idx_blks_hit > 0 or toast_blks_read > 0 or toast_blks_hit
> 0 or tidx_blks_read > 0 or tidx_blks_hit > 0 );

+------------+---------+----------------+---------------+
| schemaname | relname | heap_blks_read | heap_blks_hit |
+------------+---------+----------------+---------------+
+------------+---------+----------------+---------------+
(0 rows)
