Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
CloudAMQP
- Free tier messaging limits are low: 1-2M messages/month
- Free tier connection limits are restrictive: 20-40
- Multi-tenant plans have queue limits (200-2,000 max)
- Dedicated plans expensive at scale: up to $14,995-$17,495/month
- Extra disk space add-on at $0.35/month per GB may add significant cost
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
