psql -h 10.6.8.3 -p 5432 -U user001 -d db001

安装

可以下载后编译安装，也可以直接yum 安装

yum install -y pgaudit15_13.x86_64

修改配置文件

vim /var/lib/pgsql/13/data/postgresql.conf

shared_preload_libraries = ‘pgaudit’;

shared_preload_libraries参数修改一定要重启服务，热加载是不可以的

select * from pg_available_extensions;
create extension pgaudit;
select name,setting from pg_settings where name like '%audit%';

设置会话级别的

set pgaudit.log = 'all';
set pgaudit.log_relation = on;
set pgaudit.log_client=on;
select name,setting,source from pg_settings where name like 'pgaudit%';
