zabbix-agent2 monitoring does not fully work after upgrading to version 5.0.2, 5.0.3, 5.0.4, 5.0.5 . Some of the items in the status are not supported with an error - the only supported schemes are: tcp and unix.
The discovery item "pgsql.db.discovery" is marked as "not supported" with the above error.
After downgrading to zabbix-agent2-5.0.1, and modifying the configuration file, the discovery item and dependent items are supported again.
