Hi,
We've started getting duplicate key violates unique constraint error on one of the toast index starting last weekend. This error occurs when attempting to update a huge table.
ERROR: duplicate key violates unique constraint "pg_toast_3270368541_index"
PG version is 8.0 with postgis extension. We're planning to upgrade by end of year though.
select count(*) from pg_toast.pg_toast_3270368541;
count
---------
7663472
We've tried a couple of things:
1) Reprocess the failed extract files by resubmitting them (basically, re-run the updates). It worked so far until today where we retried two times and the update kept failing.
2) R
eindex the toast index but that still did not help.
We also run vacuum every night to avoid transaction wraparound limit, so I'm hoping this is error is not related to it..
Is there any workaround to fix this duplicate constraints error? Your assistance is greatly appreciated.
