Re: [ADMIN] Vacuum error on database postgres

[Paul B. Anderson]

I removed the duplicates and then immediately reindexed.  All is well.  The vacuum analyze on the postgres database works now too.  Thanks. It is good to know the pg_statistic table can be emptied in case this ever happens again. Paul Tom Lane wrote: "Paul B.

That's pretty odd --- I'm inclined to suspect index corruption. I also tried reindexing the table. Get rid of the duplicates (actually, I'd just blow away all the pg_statistic entries for each of these tables) and *then* reindex. Then re-analyze and see what happens. Worst case you could just delete everything in pg_statistic, reindex it, do a database-wide ANALYZE to repopulate it. By definition there's not any original data in that table... regards, tom lane .
