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.
