+Subject: [PATCH v1 1/1] Strip `$libdir` during pg_upgrade starting on 19.
+
+With the commit 4f7f7b03758 extension_control_path GUC was included,
+while some test were added, is missing to handle the hardcoded `$libdir/`
+path during the execution of `pg_upgrade` for the the installed
+extensions using the extension_control_path GUC
