1.全局设置
修改配置postgres.conf:
log_min_duration_statement=5000
然后加载配置:
postgres=# select pg_reload_conf()
postgres=# show log_min_duration_statement; log_min_duration_statement ---------------------------- 5s (1 row)
2.也可以针对某个用户或者某数据库进行设置
postgres=# alter database test set log_min_duration_statement=5000;
