I am sorry about this Jim, please understand that I am a newbie and am trying to solve long vacuum time problems and get a handle on speeding up queries/reports. I was pointed to pg_stats and that's where I am at now. I have added this into my conf file: stats_start_collector TRUE stats_reset_on_server_start FALSE stats_command_string TRUE However, these being production servers, I have not enabled these: stats_row_level stats_block_level Yes, I have re-started the server(s). It seems like I query tables to get the info. If so, are there any queries written that I can use?
Thanks for following up on this with me. Yudhvir === On 5/14/07, Jim C. Nasby <[EMAIL PROTECTED]> wrote:

I thought you were talking about the pg_stat* views, which depend on the statistics collector (that's what the stats_* parameters control). That actually has nothing at all to do with pg_stats or pg_statistics. Those deal with statistics about the data in the database, and not about statistics from the engine (which is what the pg_stat* views do...). If you want to know about pg_stats, take a look at http://www.postgresql.org/docs/8.2/interactive/view-pg-stats.html ... but normally you shouldn't need to worry yourself about that. Are you trying to debug something?
