结合postgres查询和日志持续时间

我知道您可以在postgresql.conf中使用下面的配置来显示持续时间和日志查询

------------------------------------------------------------------------------
 CUSTOMIZED OPTIONS
------------------------------------------------------------------------------

log_statement = 'all'
log_duration = on
log_line_prefix = '{"Time":[%t], Host:%h} '

然后返回如下日志

{"Time":[2018-08-13 16:24:20 +08], Host:172.18.0.2} LOG:  statement: SELECT "auth_user"."id", "auth_user"."password", "auth_user"."last_login", "auth_user"."is_superuser", "auth_user"."username", "auth_user"."first_name", "auth_user"."last_name", "auth_user"."email", "auth_user"."is_staff", "auth_user"."is_active", "auth_user"."date_joined" FROM "auth_user" WHERE "auth_user"."id" = 1
{"Time":[2018-08-13 16:24:20 +08], Host:172.18.0.2} LOG:  duration: 7.694 ms

LOG: { statement: ..., duration: 7.694 ms}
