OAuth Support in PostgreSQL

Postgres has a wide array of supported authentication methods. The strongest methods have trouble scaling across large numbers of database instances, though, and while organizations have ways to centralize user credentials -- for example by using LDAP or Kerberos -- those solutions come with their own large lists of caveats.I'm currently developing Postgres-native support for OAuth, which is a widely-deployed framework for authorizing clients using a third-party provider. I'll talk about the current state of the patchset, explain some of the elements of the design, and demonstrate what it might look like to deploy it yourself.
