I have created DB instance on RDS and used below function. It gave error while with the same PostgreSQL version on a local development machine it works fine.

create or replace function uuid() returns uuid as 'uuid-ossp', 'uuid_generate_v1' volatile strict language C;

here is the error log:

ERROR:  permission denied for language c
********** Error **********

ERROR: permission denied for language c
SQL state: 42501

I'm using this function in ruby on rails 3.2 for generating uuid for my schema.


You appear to be attempting to load uuid-ossp extension by loading the .sql file directly. You should not be doing that on any modern PostgreSQL, and it won't work on RDS.




  • Thanks Craig! To avoid re-installing the module I add IF NOT EXISTS: CREATE EXTENSION IF NOT EXISTS "uuid-ossp"; – Loren Dec 10 '18 at 19:10
