Hi @meiyifei !

So it seems that the problem is with ERROR Failed to parse pg_controldata output then. We should probably force the LANG environment to be set to C when we parse the output of the PostgreSQL commands run internally in pg_autoctl.

Thanks for your feedback. Marking this issue as a bug and assigning it to the next release, I think we should be able to have a fix that soon!
