Database restore error with PostgreSQL/TimescaleDB after upgrade from 7.0.0-7.0.4

Using pg_restore to restore a PostgreSQL/TimescaleDB backup created in Zabbix 7.0.0-7.0.4 will result in a missing base36_decode function error, causing the restore to fail. This error occurs when restoring a backup created with pg_dump.

See known issues for details on fixing this issue manually before creating the backup.

If you have not upgraded to Zabbix 7.0.0 yet, note that there should be no such issues for upgrades from pre-7.0 Zabbix versions to 7.0.5. For upgrade instructions, see Upgrading TimescaleDB schema.
