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 (seeSection 50.2) and the required callback for performing validation (seeSection 50.3.2).
Warning
Since a misbehaving validator might let unauthorized users into the database, correct implementation is crucial for server safety. SeeSection 50.1 for design considerations.
