  • Each has a real cost: Drupal steep learning curve: concepts that are implicit in WordPress are explicit and must be configured; 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: Drupal covers Structured content modelling, Postgres covers ACID compliance.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Drupal

  • Steep learning curve: concepts that are implicit in WordPress are explicit and must be configured
  • Smaller developer pool than WordPress, and correspondingly higher build costs
  • Major version upgrades have historically been substantial projects, not routine updates
  • Considerably more machinery than a straightforward marketing site needs

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

Answered from the vendors’ own pages

Drupal: Is Drupal free?

Yes, open source under the GPL. Costs are hosting, development and any commercial modules.

PostgreSQL is completely free to download, install, and use. No licensing fees, subscription costs, or per-seat charges apply. The database is open source under the PostgreSQL License. Source: https://www.postgresql.org

Drupal: Drupal or WordPress?

WordPress is faster to launch, cheaper to staff and has a much larger plugin ecosystem. Drupal is stronger when the content model is genuinely complex and permissions are strict, which is why institutions favour it.

Postgres: Are there commercial PostgreSQL support options available?

Official PostgreSQL (the project) is free. Commercial PostgreSQL services such as hosting, professional support, training, and managed database services are offered by third-party vendors, not the PostgreSQL project itself. Source: https://www.postgresql.org

Source
Drupal: Why is Drupal common in government and universities?

Structured content modelling, granular access control and multilingual support are core rather than bolted on, and those are exactly the requirements those sectors have.

Postgres: Do I need a license to use PostgreSQL commercially?

No. PostgreSQL is open source under the PostgreSQL License, which permits free commercial use without royalties, licensing fees, or support obligations. Source: https://www.postgresql.org
