Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Postgres
- Each major version is supported for only 5 years after its initial release, after which it is end-of-life
- Major version upgrades break on-disk compatibility and require a full dump and reload or the pg_upgrade tool
- New major versions ship about once a year, so staying supported means a disruptive upgrade cycle
- Minor releases contain only frequently-encountered bug fixes, low-risk fixes, security issues and data corruption fixes, so feature gaps are not addressed within a major version
- There is no vendor SLA; commercial support must be bought separately from third party professional services listed by the project
Zendesk
- AI agents operate on per-resolution billing; customers pay only when an AI agent successfully resolves a ticket without escalation
- Copilot and Contact Center features available as separate add-ons at £50+/agent/month
- Advanced routing, workforce engagement, and approval workflows limited to Enterprise tier
- Highest tier requires sales consultation and custom pricing
