PostgreSQL数据库巡检脚本说明
1、PG数据库运行方式
需要有psql客户端，运行方式如下：
psql -U postgres -h 192.168.8.8 -p 54324 -d postgres -W -H -q -f D:\DB_PG_HC_lhr_v7.0.0.sql > d:\a.html
输入密码，回车即可。
注意：
1、该脚本的字符集为utf8，若修改文件内容请使用utf8格式打开该文件。
2、巡检内容“WAL日志切换频率（需要手动修改脚本路径）”部分的“
/pg13/pgdata/pg_wal”路径需要手动修改为自己环境真实的路径，否则会报错：ERROR: absolute path not allowed
注意：
由于用户环境的版本或插件问题，如下的报错请忽略，不影响最终的结果：
[pg94@lhrpgall ~]$ psql -W -H -f DB_PG_HC_lhr_v7.0.0.sql > a.html
