Have gotten success with a dataset that failed before with ff 10.
End result:
mdstash=# select * from pgstathashindex('link_datum_id_idx');
version | bucket_pages | overflow_pages | bitmap_pages | unused_pages |
live_items | dead_items | free_percent
---------+--------------+----------------+--------------+--------------+------------+------------+------------------
4 | 12391325 | 5148912 | 158 | 191643 |
4560007478 | 0 | 1894.29056075982
(1 row)
mdstash=# select 5148912.0/158/8;
?column?
-----------------------
4073.5063291139240000
(1 row)
The index is 135GB rather than 900GB (from memory/give or take).
I'm happy so far. I'll be seeing how much more I can dump into it this weekend.
:)
Thanks muchly to the both of you. :)
