Subject: pgsql: Fix syslogger NULL-pointer-dereference in EXEC_BACKEND
Date: Mon, 08 Jun 2026 17:50:53 +0000
Message-ID: <E1wWe7h-001d4x-1n@gemulon.postgresql.org> (raw)
Fix syslogger NULL-pointer-dereference in EXEC_BACKEND
Commit 0c8e082fba8d changed the time at which MyBackendType is assigned,
breaking a careful choreography in syslogger to decide when to write
messages to its own log files. Fix by flipping a boolean at the
(approximate) location where previously MyBackendType was set, instead
of depending on MyBackendType directly.
