PostgreSQL 9.3 Amazon RDS gives error while using UUID-OSSP extension for generating uuid 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.

Use

CREATE EXTENSION "uuid-ossp";


instead.
