pg_llm

Logging Design

Overview

pg_llm uses PostgreSQL native logging directly. There is no external glog dependency.

Header

Use:

#include "utils/pg_llm_log.h"

The header provides macros:

• PG_LLM_LOG_INFO(...)
• PG_LLM_LOG_WARNING(...)
• PG_LLM_LOG_ERROR(...)
• PG_LLM_LOG_FATAL(...)

Level Mapping

• INFO -> elog(LOG, ...)
• WARNING -> elog(WARNING, ...)
• ERROR -> elog(WARNING, ...)
• FATAL -> elog(ERROR, ...)

FATAL raises PostgreSQL error. Other levels do not.

Operational Notes

• Configure log destinations and rotation through PostgreSQL logging settings.
• Existing deployments no longer need any glog build step or runtime library.
