Subject: pgsql: Log remote NOTICE, WARNING, and similar messages using ereport()
Date: Tue, 22 Jul 2025 05:22:46 +0000
Message-ID: <E1ue5Sg-0008kc-0D@gemulon.postgresql.org> (raw)
Log remote NOTICE, WARNING, and similar messages using ereport().
Previously, NOTICE, WARNING, and similar messages received from remote
servers over replication, postgres_fdw, or dblink connections were printed
directly to stderr on the local server (e.g., the subscriber). As a result,
these messages lacked log prefixes (e.g., timestamp), making them harder
to trace and correlate with other log entries.
This commit addresses the issue by introducing a custom notice receiver
for replication, postgres_fdw, and dblink connections. These messages
are now logged via ereport(), ensuring they appear in the logs with proper
formatting and context, which improves clarity and aids in debugging.
