Hi,
We have a postgres 10.7 database which reports a number of issues on user-created tables as well as system tables. Most errors are one of the following:
-- ERROR: found xmin 1888159934 from before relfrozenxid 1998177448
-- ERROR: MultiXactId 613819197 does no longer exist -- apparent wraparound
-- ERROR: could not access status of transaction 1927393975
DETAIL: Could not open file "pg_xact/072E": No such file or directory.
I have tried several of the workarounds suggested online and in the web discussion groups:
1. vacuumdb of the entire database fails with the "found xmin from before relfrozenxid" error
2. pg_dump fails with the same error
3. SELECT sql on the affected tables fails with the error. So I cannot save the table, drop it and re-create it.
4. Removed the "global/pg_internal.init" file and re-started the cluster. Still the same errors.
The database is up and running and most of the tables are accessible. But any kind of SQL on the 4 or 5 affected tables throws the error.
Is there a way to repairing the corruption in this database?
Postgres Version 10.7 on Linux(Ubuntu).
Thanks.
