Chapter 50. OAuth Validator Modules
Table of Contents
PostgreSQL provides infrastructure for creating custom modules to perform server-side validation of OAuth bearer tokens. Because OAuth implementations vary so wildly, and bearer token validation is heavily dependent on the issuing party, the server cannot check the token itself; validator modules provide the integration layer between the server and the OAuth provider in use.
OAuth validator modules must at least consist of an initialization function (see Section 50.2 ) and the required callback for performing validation (see Section 50.3.2 ).
Warning
Since a misbehaving validator might let unauthorized users into the database, correct implementation is crucial for server safety. See Section 50.1 for design considerations.
