The short version

  • Each has a real cost: Oracle Cloud the free trial gives US$300 of credit that expires when consumed or after 30 days, whichever comes first; Postgres each major version is supported for only 5 years after its initial release, after which it is end-of-life
  • They diverge on capability: Oracle Cloud covers Autonomous Database, Postgres covers ACID compliance.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Oracle Cloud

  • The free trial gives US$300 of credit that expires when consumed or after 30 days, whichever comes first
  • The US$300 cloud credit is available only in select countries
  • Only one Oracle Cloud Free Trial or Always Free account is permitted per person
  • Accounts left idle for 30 days or more are eligible for suspension or termination as abandoned
  • Always Free NoSQL Database is restricted to the Phoenix region
  • Free Tier availability is subject to capacity limits, and the published per-service capacity figures are estimates that assume the entire credit is spent on that one service

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
