  • They diverge on capability: Drupal covers Structured content modelling, PostgreSQL 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

PostgreSQL

  • Requires manual scaling across multiple machines for very large deployments
  • Performance tuning requires deep knowledge of database internals
  • No built-in graphical admin interface; command-line tools are primary method
