My bluff please ignore. I set wrong pg directory in PATH.

Uh, that is an unusual error. What PG 10 version is that, exactly? 10.4? 10.5? We added new code to test for proper server shutdown in PG 10.5, but that used pg_controldata, so I don't think that is the cause.
I think the problem is suggested in this part of the code:
/* pg_resetxlog has been renamed to pg_resetwal in version 10 */ if (GET_MAJOR_VERSION(cluster->bin_version) < 1000) validate_exec(cluster->bindir, "pg_resetxlog"); else validate_exec(cluster->bindir, "pg_resetwal");
It should be looking for /usr/lib/postgresql/10/bin/pg_resetwal --- which I bet does exist. I have no idea why this would be testing for pg_resetxlog in a path that expect PG 10. Maybe some of the directories are not the PG versions you think they are.
