Why is Postgres growing so fast?

Because many commercial applications are using it to keep costs down, and its mature, works and easy to support. I have dozens of commercial apps that use postgres, easy to upgrade and support.

Out of the top 5 databases, Postgres is the only on that had significant growth the previous year - +36 points.<p>What is causing this comparative surge in popularity?

For all the reasons shared here already, plus a compounding effect on top:<p>For every percentage point of marketshare that Postgres takes, the risk in choosing Postgres decreases, and the risk of choosing an alternative increases.<p>Risk is:<p>- Will it continue to develop, get bugs fixed, security holes patched?<p>- Will it work with all future tech my company adopts?<p>- Will it remain Open Source? - etc...

Maybe because of Supabase, Neon, etc?
