Subject: pgsql: radixtree: Fix crash when non-creator begins iteration over shar
Date: Thu, 06 Feb 2025 19:37:09 +0000
Message-ID: <E1tg7gT-005ipX-Jo@gemulon.postgresql.org> (raw)
radixtree: Fix crash when non-creator begins iteration over shared tree.
Previously, if a backend that attached to a shared tree attempted to
start iteration, it resulted in a crash. This commit resolves the
issue by ensuring iter_context is created in RT_ATTACH().
This fix applies only to v17, where radixtree.h was introduced. In the
master branch, this issue was separately resolved by 960013f2a1, which
eliminated the iter_context entirely.
