Обсуждение: Stats turned on but not being updated
Please tell me what I'm missing?
My stats Postgres 7.4 parameters are as follows:-
stats_start_collector = true
stats_command_string = true
stats_block_level = true
stats_row_level = true
stats_reset_on_server_start = true
stats_command_string = true
stats_block_level = true
stats_row_level = true
stats_reset_on_server_start = true
After turning all of these on, I restarted Postgres, then ran a table query and saw statistics appear in the following view:-
pg_statio_all_tables
However, since that first test query yesterday (and I've run several since on different tables today - some of them repeated to ensure the buffer should be populated), the statistics haven't changed. Is there another parameter, or more space, or something, that I need to allocate please? Even the stats on the system tables don't appear to change with several users on ths system.

That seems pretty odd. Look in the postmaster log to see if you can
find any relevant error messages.
