Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Argo CD
- Licensed under Apache License 2.0 per the project's GitHub repository (argoproj/argo-cd LICENSE); as open source software it has no paid tier or vendor price to compare
- The quick start installation requires the --server-side and --force-conflicts flags due to CRD size limitations, per argo-cd.readthedocs.io, a constraint the documentation states explicitly
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
