Thread: found xmin * from before relfrozenxid *

Hello PostgresSQL users and admins,

I need some help with my problem.

I looked at postgresql logs and it is littered with error messages like:

ERROR:  found xmin 3875696185 from before relfrozenxid 1599104090
CONTEXT:  automatic vacuum of table "FMS.pg_catalog.pg_database"
ERROR:  found xmin 3875696185 from before relfrozenxid 1599104090
CONTEXT:  automatic vacuum of table "FMS.pg_catalog.pg_authid"

ERROR:  found xmin 158590964 from before relfrozenxid 1599104090
CONTEXT:  automatic vacuum of table "FMS.pg_catalog.pg_auth_members"

First error occured 2 months ago. Database has never been crashed. Year 
ago it was upgraded with pg_upgrade from version 9.2.

DB version:PostgreSQL 10.4 (Debian 10.4-2.pgdg90+1) on 
x86_64-pc-linux-gnu, compiled by gcc (Debian 6.3.0-18+deb9u1) 6.3.0 
20170516, 64-bit

How can I solve theese errors?

Your bug was fixed in minor version 10.5 :-)

Plz go look at the release notes and then upgrade to latest minor
release.

Removing global/pg_internal.init may work as a temporary fix (this file
is safe to remove since it is just a cache, and will be regenerated).
Then update to 10.8.
