Thomas Munro	8d9d5843b5	oauth: Use IPv4-only issuer in oauth_validator tests ... The test authorization server implemented in oauth_server.py does not listen on IPv6. Most of the time, libcurl happily falls back to IPv4 after failing its initial connection, but on NetBSD, something is consistently showing up on the unreserved IPv6 port and causing a test failure. Rather than deal with dual-stack details across all test platforms, change the issuer to enforce the use of IPv4 only. (This elicits more punishing timeout behavior from libcurl, so it's a useful change from the testing perspective as well.)

Daniel Gustafsson	b3f0be788a	Add support for OAUTHBEARER SASL mechanism ... This commit implements OAUTHBEARER, RFC 7628, and OAuth 2.0 Device Authorization Grants, RFC 8628. In order to use this there is a new pg_hba auth method called oauth. When speaking to a OAuth- enabled server, it looks a bit like this: $ psql 'host=example.org oauth_issuer=... oauth_client_id=...' Visit https://oauth.example.org/login and enter the code: FPQ2-M4BG Device authorization is currently the only supported flow so the OAuth issuer must support that in order for users to authenticate. Third-party clients may however extend this and provide their own flows. The built-in device authorization flow is currently not supported on Windows. In order for validation to happen server side a new framework for plugging in OAuth validation modules is added. As validation is implementation specific, with no default specified in the standard, PostgreSQL does not ship with one built-in. Each pg_hba entry can specify a specific validator or be left blank for the validator installed as default. This adds a requirement on libcurl for the client side support, which is optional to build, but the server side has no additional build requirements. In order to run the tests, Python is required as this adds a https server written in Python. Tests are gated behind PG_TEST_EXTRA as they open ports. This patch has been a multi-year project with many contributors involved with reviews and in-depth discussions: Michael Paquier, Heikki Linnakangas, Zhihong Yu, Mahendrakar Srinivasarao, Andrey Chudnovsky and Stephen Frost to name a few. While Jacob Champion is the main author there have been some levels of hacking by others. Daniel Gustafsson contributed the validation module and various bits and pieces; Thomas Munro wrote the client side support for kqueue.
