Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Kronologic
- Annual billing provides savings equivalent to 2 free months versus monthly billing
- Team plan most appropriate for 5-30 person revenue teams
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
