Fix PostgreSQL Current Time Retrieval

If there is a failure to retrieve the current time in pgsql, there may be several possible reasons and solutions.

1. Incorrect time zone setting: When retrieving the current time in pgsql, it is influenced by the system’s time zone. If the system’s time zone is not set correctly, it can lead to inaccurate time retrieval. The solution is to use the SET TIMEZONE command in pgsql to set the correct time zone, for example: SET TIMEZONE TO ‘Asia/Shanghai’;
2. Database connection issue: If there is a problem with the database connection, it may lead to failure in retrieving the current time. To resolve this, check if the database connection is functioning properly, and you can try reconnecting to the database or restarting the database service.
3. Database permission issue: If the current user does not have adequate permission to access the current time, it will also result in failure. The solution is to ensure that the current user has sufficient permission to execute the operation to retrieve the current time, which can be done by granting the necessary authorization.
4. Database service error: If there is a problem with the database service, it may result in failure to retrieve the current time. To fix this issue, please check if the database service is running properly, you can check the log files or restart the database service.

If the above methods do not solve the problem, it is suggested to check the error logs and messages of pgsql for better identification and resolution of the issue.
