Postgres Security and Data Access Hardening

Original name

Original description

Use when designing, reviewing, or hardening PostgreSQL access control and data protection against the security architecture and data classification. Produces TLS and connection-security configuration, least-privilege role and grant model, row-level security policies for tenant isolation, column-level grants and encryption for PII, pgcrypto and at-rest/TDE posture, pgaudit configuration, credential and secret rotation posture, and network-exposure review. Do not use for schema design, query optimization, replication topology, or backup and restore; use postgres-schema-and-migration, postgres-indexing-and-query-optimization, postgres-replication-and-ha-readiness, or postgres-backup-and-operational-readiness instead.
