There were a lot more than this, several hundered.
Here's the general details of the DB:- Approximately 30,000,000 rows- No triggers- Table consists strictly of text,
integersand one key ( SERIAL )- PostgreSQL 7.2.3 ( yes, i'll update to 7.2.4 in the next day or so )- Pentium III
1.2Ghzwith 1Gb RAM running RedHat 8.0 ( Not my machine! )
Here's the lead up to events:
- Two days ago I DELETE'd approximately 7 million rows- I proceeded to vacuum, but it was 'terminated' by another admin
approximately12 hours later- I restarted the vacuum, which resulted in the following stats:
NOTICE: Pages 701193: Changed 8459, Empty 0; Tup 21042082: Vac 0, Keep 0, UnUsed 32056923
- I ran the DELETE script again which purged another 200,000 rows ( approx )- I proceeded to vacuum, the table in
questionreturned the following stats:
NOTICE: Pages 704754: Changed 9599, Empty 0; Tup 14385034: Vac 0, Keep 207650, UnUsed 38884420.
- Today I dropped an index off the table, ran the DELETE again, removing 457,636 rows- Vacuum dumped the above
NOTICES. Final output for the table is:
NOTICE: Index xamefiles_k_key: Pages 187175; Tuples 14521716: Deleted 666334. CPU 8.92s/14.11u sec elapsed
1306.20sec.- The vacuum is still going along fine.
Backups are proceeding without incident ( using pg_dump )DELETE's are proceeding without incident
Hope this is enough information.
Kind Regards.
