postgREST log add customs fields

[Dementor7]

Hi all , I need one help
This is my postgREST log format

127.0.0.1 - postgres [10/Jan/2024:10:55:27 +0530] "GET /subscription_user_role_mapping?UserId=eq.110000 HTTP/1.1" 200 - "http://localhost:3000/" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36"

127.0.0.1 - postgres [10/Jan/2024:10:55:28 +0530] "GET /subscription_client_users?ClientId=eq.1100001 HTTP/1.1" 200 - "http://localhost:3000/" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36"
