From d6e56c7259088529ae7a114f57f4dc875697dd97 Mon Sep 17 00:00:00 2001 From: Euler Taveira Date: Tue, 4 Nov 2025 17:18:20 -0300 Subject: [PATCH v7 1/3] log_min_messages per process type Change log_min_messages from a single element to a comma-separated list of elements. Each element is type:level. The types are archiver, autovacuum (includes launcher and workers), backend, bgworker, bgwriter, checkpointer, ioworker, postmaster, syslogger, slotsyncworker, startup, walreceiver, walsender, walsummarizer and walwriter. A single log level should be part of this list and it is applied as a final step to the process types that were not informed. The old syntax (a single log level) is still accepted for backward compatibility. In this case, it means the informed log level is applied for all process types. The default log level is the same (WARNING) for all process types. --- doc/src/sgml/config.sgml | 42 +++- src/backend/commands/extension.c | 2 +- src/backend/commands/variable.c | 208 ++++++++++++++++++ src/backend/postmaster/launch_backend.c | 2 +- src/backend/utils/error/elog.c | 2 +- src/backend/utils/init/miscinit.c | 2 +- src/backend/utils/misc/guc_parameters.dat | 10 +- src/backend/utils/misc/guc_tables.c | 21 +- src/backend/utils/misc/postgresql.conf.sample | 2 + src/include/postmaster/proctypelist.h | 42 ++-- src/include/utils/guc.h | 6 +- src/include/utils/guc_hooks.h | 2 + src/test/regress/expected/guc.out | 54 +++++ src/test/regress/sql/guc.sql | 18 ++ 14 files changed, 372 insertions(+), 41 deletions(-) diff --git a/doc/src/sgml/config.sgml b/doc/src/sgml/config.sgml index 405c9689bd0..62d6c0d36a2 100644 --- a/doc/src/sgml/config.sgml +++ b/doc/src/sgml/config.sgml @@ -7069,7 +7069,7 @@ local0.* /var/log/postgresql - log_min_messages (enum) + log_min_messages (string) log_min_messages configuration parameter @@ -7078,14 +7078,38 @@ local0.* /var/log/postgresql Controls which message levels are written to the server log. - Valid values are DEBUG5, DEBUG4, - DEBUG3, DEBUG2, DEBUG1, - INFO, NOTICE, WARNING, - ERROR, LOG, FATAL, and - PANIC.
