The short version

  • Each has a real cost: GitLab baseline requires 8 vCPU and 16 GB RAM for single-node installations; resource-intensive; 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: GitLab covers Git repository management, 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.

GitLab

  • Baseline requires 8 vCPU and 16 GB RAM for single-node installations; resource-intensive
  • PostgreSQL is mandatory; no support for alternative databases
  • Redis or Valkey cache required; adds infrastructure complexity
  • High-availability deployments require inter-node latency below 5 ms; difficult to achieve across geographically distributed sites
  • Requires self-hosting and maintenance; GitLab.com SaaS only available to GitLab team members for administration

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
