I think the below change is not relevant to this bug right? diff --git a/src/test/recovery/meson.build b/src/test/recovery/meson.build index 209118a639..6e9f8a7c7f 100644 --- a/src/test/recovery/meson.build +++ b/src/test/recovery/meson.build @@ -39,6 +39,7 @@ tests += { 't/031_recovery_conflict.pl', 't/032_relfilenode_reuse.pl', 't/033_replay_tsp_drops.pl', + 't/100_bugs.pl', ], }, } -- Regards, Dilip Kumar EnterpriseDB: http://www.enterprisedb.com
