Re: ERROR: found xmin from before relfrozenxid

To avoid a dump/restore, use this:

psql -o /dev/null -c "select * from table for update" database 

Using the last releases of the major versions solve the bug for me.

Best regards

Hey,

The logs are full of info that I cant share. However, it full of the next messages : 

ERROR:  found xmin 16804535 from before relfrozenxid 90126924

CONTEXT:  automatic vacuum of table db1.public.table_1"

...

What I'm trying to understand here is if the bug was fixed or not. In the first time it appeared the dump and the restore solved the issue. However, is happened the second time on a different table. So basically I'm trying to understand how to solve it permanently. 

the dump command ; pg_dump -d db -U username -t table_name -f table.sql

I dropped the old table and restored it :

drop table table_name;

psql -d db -U username -f table.sql

Hello,

Could you provide more details (logs...) and remind how you perform
database dump/restore?

This will help community to help you ;)
