Resolving gen_random_uuid() Error with PostgreSQL While Implementing CI When configuring CI with GitHub Actions, I encountered the following error:

PG::UndefinedFunction: ERROR:  function gen_random_uuid() does not exist

This error occurred because the gen_random_uuid() function is not available in PostgreSQL versions older than 11. UUID generation functions were only available through external modules like uuid-ossp and pgcrypto in these older versions.

To resolve this issue, I upgraded to PostgreSQL 13, which includes the gen_random_uuid() function to generate version-4 UUIDs. After upgrading, the error was resolved.

#rails #postgresql #uuid #ci-cd #github-actions
