Evaldas> Hello PostgresSQL users and admins,
Evaldas> I need some help with my problem.

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

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

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

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

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

Evaldas> How can I solve theese errors?

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.
