PostgreSQL 18 introduced native OAuth 2.0 authentication support, marking an important step towards modern, centralized identity-based access control. However, since every identity provider implements OpenID Connect (OIDC) slightly differently, PostgreSQL delegates token validation to external validator libraries. This is where Percona’s [pg\_oidc\_validator](https://github.com/Percona-Lab/pg_oidc_validator) extension comes in - it bridges PostgreSQL with any OIDC-compliant Identity Provider.
