Eu posso ajudar você a escrever o log de acesso do nginx ao postgres. Vamos lá formato de registro Nginx
log_format logtodb '$time_iso8601;$http_host;$remote_addr;$http_x_forwarded_for;$request_method;$request;$status;$body_bytes_sent;$http_referer;$request_time;$upstream_http_x_cache;$uri;$upstream_addr;$host;$upstream_response_length;$upstream_status;$server_name;$newurl;$upstream_respons
e_time ';
access_log /var/log/nginx/access_logtodb.log logto
db;
Vamos.
Configurar o syslog-ng
nano /etc/syslog-ng/syslog.ng
