postgres-security-and-data-access-hardening

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.
