Good morning,
We are at Postgres 7.4.5. I have encountered inaccuracies
after reindexing related to the statistics posted back to the PG_CLASS table
For instance:
1. We have a ‘queues’ table with 6 indexes. We are at 110,000 rows in this table.
When I reindex, the RELPAGE count decreases as expected but the RELTUPLE
Count increases to about 132,000 in all indexes. I check and there are still
Only 110,000 rows on the table.
2. We have a table that is quite volatile in its numbers, ranging from 100 to 6 million rows.
Last week we were at 50,000 rows but PG_CLASS.RELTUPLES showed 6 million for
The indexes. I reindexed and, again the RELPAGES count went down but the RELTUPLES
Number went down to just 3 million.
Again a count after reindex gave the actual row count at 52,000.
Does anybody have any insight why this is happening and what I can do in the short term?
I know we are at a back-leveled version so perhaps the long-term answer is to upgrade.
Thank you,
