Friday tickets and 6 TB of WAL: a day in the life of a Postgres Professional support engineer

Technical support at Postgres Professional involves both troubleshooting and engineering tasks, requiring deep product knowledge and the ability to replicate issues in test environments. A notable incident involved a client whose pg_wal directory grew to 6 TB due to a checkpoint process failure, which was resolved by disabling the archive_timeout parameter. Clients typically have a strong technical background, but support engineers must also communicate effectively, especially with stressed clients. Essential skills for support engineers include a thorough understanding of Postgres Pro, operating systems, networking, and programming. Opportunities for growth within technical support are abundant, and the future may see AI taking on simpler tasks while complex cases remain for human engineers.

Can’t sign up for Windows 10’s extended updates? Here’s why that might be – and what you can do about it

Users of Windows 10 are facing challenges with Microsoft's Extended Security Updates (ESU) program, which is not functioning properly for some due to regional limitations and technical glitches. These issues prevent certain users from enrolling in the program, which is intended to provide critical security updates. Some users report that the ESU rollout is unavailable in their area, while others are blocked from signing up due to bugs misidentifying their Windows 10 PCs. While some have attempted to resolve these issues using the Media Creation Tool for an in-place upgrade, caution is advised, and backing up data is recommended. Users are also considering waiting for Microsoft to address these enrollment challenges, although the first security update under the ESU program is set to roll out soon, leaving those unable to enroll feeling vulnerable. A suggestion circulating on platforms like Reddit involves accessing the ESU enrollment via a specific link in Microsoft's end-of-support portal, which has reportedly helped some users bypass standard enrollment issues. However, many users express frustration as the October 14 End of Life deadline for Windows 10 approaches, and some may consider upgrading to Windows 11 if ESU issues persist. Additionally, even users who have successfully enrolled in the ESU program sometimes receive incorrect notifications indicating they are not supported.
