From 28134ca74917a72d0c1c8b3cd640a9b50264524b Mon Sep 17 00:00:00 2001 From: Masahiko Sawada Date: Wed, 20 Jul 2022 17:25:11 +0900 Subject: [PATCH v3] Improve description of XLOG_RUNNING_XACTS. Previously, the description of XLOG_RUNNING_XACTS showed only top-transaction XIDs and whether subtransactions are overflowed. This commit improves it to show individual subtransaction XIDs. This impacts the format of pg_waldump or anything using these description routines, so no backpatch is done.
