Steps to reproduce:

  1. Run PgPool-II 4.7.0.

  2. Execute pcp_proc_info.

  3. Check the main PgPool log.

    4. =

Current behavior: Even with log_min_messages =3D warning and log_pcp_messa= ges =3D off, these messages persist. It seems like a hardcoded pool_log or fprintf in the source code of the PCP chil= d handler.

Expected behavior: Internal structure debugging like pi->node_ids should only = appear when debug_level is high or during development builds.<= /p>

Environment:

  • PgPool-II version: 4.7.0

    • OS: Ubuntu (Docker)
