[18.0][ADD] auditlog_clickhouse_read: add FDW read mode#3543
Conversation
Add new module auditlog_clickhouse_read to display audit logs stored in ClickHouse through PostgreSQL FDW. The module adds a switchable read mode for standard auditlog views, protects auditlog models from write operations while FDW read is enabled, and provides safe enable/disable flow with schema checks and rollback support. Also add test coverage for FDW mode switching, configuration guards, DDL helpers, and readonly behavior. Task: 5248
