Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Kong

The Plus plan includes 1M API requests a month and charges $200 a month for each additional million
Plus is capped at 10M requests a month, so growth past that forces an Enterprise contract
Plus limits published APIs to 20 and includes one Developer Portal, with a second at $200 a month
SSO and audit logging are Enterprise only
Enterprise pricing is custom and billed annually

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
