Question

我指的是https://github.com/zubkov-andrei/pg_profile来生成类似报告的awr。

我遵循的步骤如下：

1）在postgresql.conf (located inside D:\Program Files\PostgreSQL\9.6\data)

中的参数下方启用

track_activities = on
track_counts = on
track_io_timing = on
track_functions = on

shared_preload_libraries = 'pg_stat_statements'
pg_stat_statements.max = 1000
pg_stat_statements.track = 'top'
pg_stat_statements.save = off

pg_profile.topn = 20
pg_profile.retention = 7

2）手动将以pg_profile开头的所有文件复制到D:\Program Files\PostgreSQL\9.6\share\extension

3）从pgAdmin4控制台成功执行以下命令

CREATE EXTENSION dblink;
CREATE EXTENSION pg_stat_statements;
CREATE EXTENSION pg_profile;

4）要查看已经存在哪个节点，我执行了SELECT * from node_show(); 导致

node_name as local
connstr as dbname=postgres port=5432
enabled as true

5）要创建快照，我执行了SELECT * from snapshot('local'); 但低于错误

ERROR:  could not establish connection
DETAIL:  fe_sendauth: no password supplied

CONTEXT:  SQL statement "SELECT dblink_connect('node_connection',node_connstr)"
PL/pgSQL function snapshot(integer) line 38 at PERFORM
PL/pgSQL function snapshot(name) line 9 at RETURN
SQL state: 08001

一旦我能够生成多个快照，那么我应该能够生成报告。

Answer 1

只需使用SELECT * from snapshot（）

查看该函数的代码。它以node为参数调用另一个。

Postgresql pg_profile在创建快照时出错
