Re: [Condor-users] How to shrink quill database?

Hi Greg,

Here's the output of the command...

quill=# select relname, relpages from pg_class order by relpages desc
limit 20;
             relname             | relpages 
 pg_toast_16857                  |   169365
 jobs_horizontal_history         |    70703
 jobs_vertical_history_pkey      |    55845
 jobs_vertical_history           |    51525
 machines_vertical_history       |    20161
 jobs_horizontal_history_pkey    |      666
 transfers                       |      351
 jobs_hor_his_ix1                |      298
 jobs_hor_his_ix2                |      254
 runs                            |       91
 error_sqllogs                   |       87
 pg_statistic                    |       69
 matches                         |       46
 pg_proc                         |       44
 pg_attribute                    |       43
 pg_toast_16857_index            |       43
 pg_attribute_relid_attnam_index |       42
 pg_proc_proname_args_nsp_index  |       41
 pg_depend                       |       36
 events                          |       29
(20 rows)

So pg_toast_16857 is the culprit, however...

quill=# SELECT pg_size_pretty(pg_total_relation_size('pg_toast_16857'));
ERROR:  relation "pg_toast_16857" does not exist

Can pg_toast_16857 be emptied without crippling the database? What do
you advise?

Sometimes, postgres seems to grow without bounds.  Let's first see what 
tables or indexes are the problem.  Run the following interactive psql 
query, and it should be clear where the bloat is:

select relname, relpages from pg_class order by relpages desc limit 20;
