Steps to reproduce:

1. Install zabbix-agent2: 5.0.2
2. start zabbix-agent2

Result:

Error in the logfile: invalid plugin Postgres configuration: Cannot assign configuration: invalid parameter Plugins.Postgres.Password at line 5: unknown parameter

same for:

• Plugins.Postgres.Host
• Plugins.Postgres.Port
• Plugins.Postgres.User
• Plugins.Postgres.Password

This worked with zabbix-agent2 (Version: 5.0.1) and the documentation lists those parameters as valid (at least it lists Plugins.Postres.Host and Plugins.Postgres.Port): https://www.zabbix.com/documentation/current/manual/appendix/config/zabbix_agent2
